First order, Ordinary Differential Equations. 

There are three main types of first order ode 1. Separable ODE 2. Linear ODE 3. Exact ODE Other types of first order odes which can be found in textbooks can be reduced to this three types There are three ways of reducing equation to another type 1) substitution 2) integrating factor 3) introducing a parameter

You are saving an engineer's GPA with this video 🥺🥺🙏 Thank you very much

you just taught me 3 weeks worth of lectures in under an hour. thank you so much for this

This is great. Clear and so easy to follow step-by-step. Excellent overall teaching methods 👍🏼

Thank you so much for this sir, words really cannot explain how thankful I am😭😭

Fantastic video! Spend days on this and now got it within less than an hour. Thank you!

This is one of the best and complete videos explaining the methods on how to solve ODEs in RU-vid. KUDOS to you LEO!!!

Big thanks teacher LEO!!! Your lesson was adorable and thank you for great 48 minutes.

Great and crystal clear explanation,,,,, looking forward to watching your tutorials on more calculus problems.

This video is ELITE! coming in clutch during finals my friend. Thank you!

THANK YOU SO MUCH. YOU SAVED ME BIG TIME!!! I have a quiz tomorrow and I didn't understand how my teacher explained it. I'm so blessed that I found your video. You also gave a lot of bonus which I really appreciate. God Bless You!!!

Thank you Sir. Wonderful. Your voice was gentle and smooth; no tension, no rush.

Thank you Sir Leo. You've made it easier for some of us to understand this topic

I have my final in 2 days and you prepared me in just 1 hour. Thank you.

Just amazing. The fact that you managed to crop all the methods of solving differential Equations while exactly showing the nature of such DE with ease and simplicity while cracking down complex to simple and comprehensive responses warms my heart. I managed to spent time putting down in details every word you said in every step, while drawing examples and solutions to each example given in each Method in my book. I'm in awe 📍📍📍🙌 Thank you Leo.

I learnt more from you than my classroom and personal tutor combined ,thank you !

there are also DDE , difficult differential equations...................hahahahahahahha

Outstanding performance sir...MashAlah

awesome video very thorough and straight forward. this will save me from failing my summer semester thank you brother

I'm not a math student, tricks like raising both sides to the power of e were awesome :D I don't recall that from anywhere. Useful stuff! I never had differential equation handling in school or in university (never ran into them much)

Dig this channel because it’s like Viktor from Arcane teaching me calculus. Great content.

thanks, Fantastic video! Spend days on this and now got it within less than an hour

THANK YOU for this video! This was incredibly helpful, I feel so much more confident!

Much thanks! My professor didn't explain it as clear as you did!

My 2ND Year MATH exam is next week, this has helped me a lot!!! THANKS.

excellent! Hope you have prosperous growth in your endeavors. You helped me learn during the pandemic.

Out of words...you are just so amazing and helpful...I have a CAT today and am confident. Thank you once again.God Bless you

Thanks man. You have break it down easier for me.

Professor Leo thank you for solving First Order Differential Equations by using Separable, Linear, Homogeneous and Exact Methods. All these important methods can only help current and future students in Differential Equations.

Thanks alot for this lecture.. u made it very easy to understand the concepts in very little time 💗

You're literally a beast at explaining Maths....your mind map for #4 is epic.

This was a great explanation! Learned a lot! Thank you!

EXACTLY my syllabus THANK YOU

Very glad to reach this lesson. Truly appreciated. Hope you good time.

what an incredible elaboration!clearely understood ,thank you!

Thx very much ur vids are very easy to understand.

As a visual learner the flow chart is very helpful

awesome how easy and very explaining way of your teaching glad i found out this video really nice keep it up

You've saved my mids. Thanks alot

Wooow thank you ,everything was just clear and easy to understand

at the end of the lesson you showed how to remember sin and cos derivative and integral with a cirle. Thats the best way I have ever seen. Thanks a lot.

You are one of the best I hv come across

Thanks for the good work done, we appreciate 🙏🙏🙏.

100% video, nothing left out

Amazing video brother, it helps a lot ❤Thank you

you're amazing, i have a test tmrw and you explained 4 lessons in 48 min. thank you so much!

superb sir! I finally understood the lesson thanks to you sir🙏🙏

Thank you very much , this video was really a blessing and easy for me to understand LOL

Simply...BEST OF THE BEST! AWESOME!

For the exact equations, you should call the little functions just M and N. My and Nx are the partial derivatives of M and N

Your video is so easy to understand. Thanks a lots LEO

Thankyouuu sooo muchhh. Without you, I would've failed my exam. The video was very helpful. Thank you again

Very helpful explanation, thanks!

Thank you for making this video. It was very helpful 🙂♥️

A very good lecture. Thanks.

This is really helpful, thanks!!

Sir you saved me, best explanation yet!

I LOVE UR VIDS!!! i have a 92 in my class now keep up the great work!!!

Thanks much 4 your lecture

thank you for the great work, its been really helpful.

Thank you for this light... clarity has been achieved.

Wallah, it is slow but perfect..everything is clear...thanks a lot

the best one as the building block for ode. highly recommend

Beautiful presentation

❤ you're the boss sir, keep it up.

Beautiful presentation Great work Please can you do a video on fromation of differential equations

Best 48 minutes I have spent on RU-vid!

Thank you so much, you really help me to understand my WHAT-IS-THAT 5-hour lecture.

Thank you so much, LEO. I've got a quiz tomorrow. I think I'm going to pass it!

Great lecture, thank you

Great sir..... 😍👍

I will be having quize test and midterm exam soon on this topic you summarised everything clearly I appreciate Thanks dear sir 🙏

Wonderful, great

Thank you sooooooo very much sir God bless you abundantly

thankyou LEO, you saved my life, there is a CalC BC test coming up soon, I was thinking how to not fail the second test in my high school senior year

great video!!!! super helpful

Thank u so much

Exactly what i wanted, dankooo👏

Thank you so much I understand because of this video. ❤️

Very good explanation. Small correction (as I think): at about <a href="#" class="seekto" data-time="585">09:45</a>, on the top right of the screen, the constant k is missing on the right side of the equation. Thank you

very well explained...

very useful. thank you

this was very helpful ,thankyou

Thank you, Sir !!

really very helpful to me.thank you so much for your method of lecture.

Tnxs , God bless you
