❖ Derivatives of Logarithmic Functions ❖ 

These 5 to 10 min videos teach me more than my teacher's 50 min lectures lol

This dude is certainly among the very best ones I've seen over all internet when it comes to explaining in very effective, simple ways.

i dont freaking understand why college professors and TA's can't teach like this.... i mean seriously

You and Khan Academy saved my life

have a math test in 3 hours and i learned nothing from class, these videos are like a gold mine

Man you are great! Much clearer than my college Calculus teacher who I pay money to learn ABSOLUTELY NOTHING from! You cut out all the BS and fancy lingo and just explain it where it can be easily understood. AT this moment, YOU ARE SECOND NEXT TO GOD! THANK YOU!!!!!

The person teaching makes such a difference on how you learn. I unfortunately have the teacher at school that has no time management and we are usually rushing so most of the time so class is lost and to busy copying the notes, but now that i have found you my good sir self teaching and all that junk should be easier with you. Thank You.

Your videos are some of the best I have found. Many out there are hard to understand but yours are straight to the point and very thorough in many types of questions. I'm basically using your videos as one of the main resources for my Calculus class. Thank you!

Man, I want to thank you for your great effort to post these videos on RU-vid for free. I'm now in the middle of my semester, taking calculus 1 and without your help in your videos, I would be totally lost. I can't understand from my professor at class at all because she teaches too fast and rush through the problems. I have a midterm Calc 1 exam on derivatives after 6 days and you are really helping me with this. You make it so clear to understand in your videos and you honestly should get paid for this tremendous effort to help anyone for free on RU-vid. Thank you Sir!

I graduated a year ago and in economics and now I’m in sales and making food money never have to use this again. It’s only a matter of time until you never have to do this again. You’re almost there

I was stuck on a problem for over 30 minutes and it took 20 seconds of watching your video for me to see the light. You're a savior!

Thank you. He explains it simply and clearly, perfect for review after you don't quite get the lesson in class.

Okay, I have been sitting here frustrated for hours trying to understand derivatives of logarithmic fuctions. I watch 3 minutes of your video and all my problems are solved....THANK YOU.

A special thanks goes to you man! You have just rescued a student in Egypt - Arab Academy for Science, Technology & Maritime Transport. Thanks again, Wish me luck with my Calculus1 exam tomorrow! :)

Well I've been watching your videos non-stop for about 14 hours.... have my final in an hour and a half. I feel a lot more confident after watching your videos, thanks so much for taking your time to make these. You are helping so many students far beyond what you can even imagine. Thank you so much!

Who needs a math teacher when we have you. Honestly you are amazing👏🏼👏🏼👏🏼. Your videos are clear and easy to understand. Thank you soo much 💖💖

I'm halfway throught my Calculus 2 class for this semester and I've learned absolutely nothing for my teacher. These videos, with a little bit of help from MyLabsPlus, has helped me more than I could imagine. At first I thought I wasn't meant to understand any of this, but then I realized I wasn't getting the right and relevant information. It's sad, seeing so many stories of people having to go to youtube for 5-10 minute videos because their teachers/professors aren't really teaching us anything in our 1-2 hour lectures. Damn shame.

WHY ARE YOU SUCH A GOOD TEACHER. It brings tears to my eyes

Thanks so much. Been having trouble with this section and you explained it in an easy to digest way.

Yep, I still get more out of one of your videos than I do out of an hour of "lecture" in class. Thank you for that!

Wow, using the properties of logarithms makes it so easy! I can't believe I didn't think of that and that my teacher didn't even mention it!!

Thank you for uploading this video, I have learn more from you in 9 minutes than what I learned in 1 hour with my profesor. I wish you best of luck in your career. I have already shared this video with my classmates.

You are unbelievably helpful! Thank you so much for the examples! You make learning calculus much easier, my only regret is that I didn't find your youtube channel sooner!

This video taught me more then 3 weeks of lecturing. THANK YOU!!!!

I don't know if you still do this stuff, but your videos have saved my life. Thank you so much!

omg, thank you SOOO MUCH, I was SOOOO lost in class today when my professor tried to explain this, took him like an hour to do so and I didnt understand, took you only a couple of seconds to get the message through and make me grasp the intuition

You're amazing. Every Calc class I take, I come home, watch your videos and then finally understand it.

I wish i had discovered you before... You are much better than my math professor .. Thanks a million ..

I love how you just call it "complicated stuff." helps me remember what to do easier for some reason.

you take the lessons that i have in class and explain them well, perfect enforcement and learning of ideas. you say it how it is

That subtraction trick helped so much. Thanks.

been working on this stuff for hours and came across your videos. seriously incredible!!! Wish I discovered you 2 months ago THANK YOU!!!!!!!!!!!!!!!!!!!

This really helped me on one of my homework assignments that I was stuck on for what seems like forever. Patrick, you make this so much easier!! :-)

Awesome videos, they are a huge help and you really explain it well. Keep up the great work!

i went from a C- in math to a A in the span of 1 term. I don't pay attention in class because i know i can come home to the best teacher of Calculus. You have saved my senior year grade Pat and for that i am infinity grateful

PatrickJMT is a true hero.

THANK YOU so much for making these math videos, you explained so much better than my one hour lecture that is given by the professor. Life Saver!

These videos are life-savers, thank you patrick

I would never have survived college without you man. You're better than most of my lecturers!!!

Calculus is already hard as it is. Throw in a thick accent, it's even harder to understand! Thank you so much Patrick for making it SIMPLE for me to understand. I sit in lecture for 50 minutes scratching my head and wondering what my professor is trying to get it but you make it so much easier!!!!

Bravo Sir. Thanks alot.I study in french but I get my concepts better in your videos. Thanks once again

THIS IS A BLESSING

Wow. Watching this makes it seem a hell of a lot more simpler than my professor was explaining it. I like how you use the word "stuff" to describe the numbers inside , lol. This is easier to understand, thank you so much.

You have helped me so much through Pre-Calc. I don't know why but you explain a lot better than my math teacher. I'm taking AP Calc and I have the same teacher as I did before :'( THANK GOD I HAVE YOU! :DDD

Perfect. All the valuable information right at the beginning and the explanations after. All I needed was the formulas. Taking Calc II after forgetting all the memorization from Calc I is not fun. Not to mention it's a summer course and it's the entire semester in 19 days.

i got a 100 on my calc exam!!! thank u so much! with organic chemistry im not able to devote much time to calc, only study once a week, u seriously helped me in understanding the concept. thanks again!

it feels so great when you solve all the examples before he does :) Thx for these amazing videos!

Thank you dude. Your videos are really easing my pain with my AP Calc class. Thank you for taking the time to do all this.

You sir should receive the person of the year award for all these videos you have made, very helpful.

ur wow! God bless u 4 dis videos i love ur teachings

U're the best. Thanks to your vids I understood everything about derivatives! Thank you!

Thank man. I've been scratching my head trying to figure this stuff out.

This channel helps me past my tests, Thanks!

good luck man!!!! i have one on tuesday and this guy really helped me allot in my math, if i feel dont feel someday going to class, i remember that i've got an awsome math teacher to see patrick you are IMBA!!!!!!!!

you and mathbff are just gold, i knew nothing 2 days before the exam and ended up getting a B plus. if theres anyway ican support either of you please let me know

the tutorials are a GREAT help. Thankyou.

i love you Patrick!! You are the king of math!

Thats so cool that he uploaded this in October 2007 and here we are October 2013 still learning from him

Today is the 21st of May 2012. Finding your videos extremely useful, and because of you, I've probably passed one of my bridging maths units for engineering! Cheers from Perth, Australia!

This guy just explained what my “teacher” (she doesn’t really teach... so idk why I call her one) took a few weeks to explain, better than she did, and in 10 minutes. Thank you dude!!!!!!!!!!!!!!!!!!! Now let’s just see if I can remember all this for tomorrow 😂

you are such and amazing teacher. you are always so calm and sweet in your videos and don't rush things. Thank u.

You seriously have a talent for explaining. I know you don't like being called a genius, but your skills at explaining, especially in front of a camera, are godly.

congrats :) keep up the good work!

Seriously awesome vids patrickJMT seriously thank you!

Well explained in a very professional manner EXCELLENT

@patrickJMT i love you man,,, u help me pass my TEST ALWAYs thanks alot , keep up the good work. people like you change the world.

YOU ARE THE SAVIOR OF MY CALCULUS GRADE. GOD BLESS YOU!!!

Thank you! I'm in AP Calc, and I've never needed help with math before, but I got tutor this year because I got a C- first quarter. My teacher moves SO fast through the material, it's insane (in my opinion). I think all the kids around me have taken summer math classes or something because they rarely have questions. We're on chapter 5 now, but I just figured out chapter 4! WTF?! (I got another C- on the previous chapter's test.) Anyways, these videos have helped a lot.

you are a freaken genius! thanks for the help, definitely needed this video for my test! thanks again!

I can sit through an entire lecture and not know wtf is happening... but 10 minutes in front of one of your vids and it all makes sense. I wish you taught at U of T, I wouldn't hate calculus.

Calc quiz in 2 hours, this made 100% more sense than my lecture AND the textbook.

Saved my life with the last example, I probably would of made that mistake on a test.

Thank you for your beautiful explanation.

This is my first time using one of your videos, but I'll be back since I need to pass Calc I. Great vid.

Thank you! You made it so easy.

Thank you Patrick, you are a life saver..#Love From South Africa

i wish i had bumped unto des awesum vids earlier...nvr mind. u make maths so much fun and easy! Thanks a lot. :) dunno y, we cnt hv cool and knowledgeable teachers lik u who help us grasp things in 5 min!

Thank you so much. I would fail calculus if it weren't for you because all of my teachers have been horrible!!!!! You're a grade and life saver!

very good! Perfect for review or even learning the topic right off the bat. TY!

Very helpful, now I fully understand it thank you. I'm ready for my calculus final

Thank you for the informative video!

thanks for the tips man, it really helps :)

Thanks for the video! It helped a lot.

Thank you soooo much for making this video!!!

Thank you so much for this! Really appreciate it!

i love you. thanks for making these super helpful videos!

Patrick! man do you make finals less stressful!. Every time i want have troubles in calculus i go only to your videos, im recommending them to my friends and so far they like them as well.

You're the greatest... It's people like you who are really making a difference in the world, STAY COOL

Way better explanation than class. Thanks!!!

You, sir, are awesome. Thank you :) I like the one before the last one, pretty tough.

Thanks man. I love your videos, those r really helpful. U r like my first choice math teacher.

Great, you are genius man. And your hand writing also amazing. Thanx for your efforts

Best math teacher ever!

Love your teaching! Thanks alot

10 years after and this video is still new.

Good job! Attention: If you simplify first for the last problem, the answer has little bit different form: 2xln(1+e^x)/[(1+e^x)(ln4)^2]

thank you sooooo much. you saved my life

Great video man. Thanks!

thanks man!! ur videos are brillant...and u as well!!!

thank you so much for making this
