@@supremek3103 He occasionally makes mistake, but show me a teacher who does not ever make a mistake, and I will show you someone who may not be human!
Bro, you just explained this stuff in less than 20 minutes 110% better than my math teacher who had an hour and a half. You are truly a lifesaver. Thanks.
My math teacher never taught it whatsoever. The first time I ever saw it was in final year on my mid-year exam paper. She was supposed to teach it 2 years prior. I swear we are better off with RU-vid tutors... 🤧
This guy helped me through my whole high school life, I seriously didn't think I'd come back to this channel in college too, you're a life saver bro😂😭😭
I've always thought that one's ability to learn dropped off after reaching adult. I must have had some terrible teachers in highschool. Im ,45yo and this has so clear. Your skills as a teacher probably surpass math ability.
im basically using khan academy for sat exam but sometimes i cant understand the explanation there, so i watch here quiet often and now i am confident for my exam in may!!! !!! thank you !! love from Istanbul,Turkey
Your videos have helped me to improve drastically (from 35% to 95%) in my matric certificate and I'm positive that in University you are going to be very useful to me
You know what, i've been using this chanel since i have first know you while i was still student in college now i am a teacher already i recommend your chanel to all of my students always You're such a great help in my math life.
I wish I found you before my grades closed because now my grade doesn’t properly reflect my understanding because you just make everything so much easier!! But from now on I guess it’ll be better since I found you 🥺
This is the most helpful math video I think I've ever watched. i left class yesterday feeling completely stuck and Like i didn't belong in that course, but watching just your video cleared everything up for me. THANK YOU SO MUCH!!
one thing i'll hate when i finish my math A levels is that i'll no longer get to watch your videos :( you've been saving my ass in maths for years but i'm graduating next year. i'll miss you :((
This helped me a lot, I didn’t do too well in my radians test. This clarified so much I was confused on and now I understand radians, finally!!! I also used your cosine, sine, and tan videos as well when I was stuck on that too. Your videos really help, thank you so much☺️☺️💞
RU-vid is great because I can spend 45 mintues in class trying to figure something out while the professor steams ahead and by end of the class, I'll never figure it out. Then I spend 3 minutes on youtube and make more progress than the entire class... I love online tutors. These guys are the real professors but probably don't get paid near as much.
Nice clear lesson! It also helps to use the formula for circumference i.e 2πr = circumference of circle = 360 degs. This works out to r = 360 degs / 2π which reduces to the same r = 180 degs /π. Thus 1 radian = 180 degs / π
bro this channel has saved my grade in so many subjects, like I took my chem final yesterday and Omg if I hadn't been watching his videos I'd have definitely failed bro- Im abt to go take my functions final and I have the confidence that I am not gonna fail this thanks to those videos. literally teaching me bettet than my teachers ever could
Dude tysm im in grade seven and all of my classmates are on Triginometry while im stuck doing Algebra 2. I wouldn't be able to understand a thing without you
@@afrorevolution6125 ikr?? But my teacher teaches us a lot of math and I've had him for two years. By the end of grade 6 I learned algebra one and half of algebra two so he taught us more math the next year
the only way to help this guy back is to watch the ads that popping out on his video and I'm going to write this comment to all of his video for you to know you can help him back by just watching his ads
@First Name Last Name yasss well done ! Keep it up , I hope I do just as well, I'm a 1st year in chemical engineering, so idk what to really expect in terms of difficulty 😂
Quick mechanical tip: to convert any angle from degrees to radians, divide that angle by 180. You will get a fraction, now write pi next to whatever number is in the numerator and boom, there is your angle in pi radians. And if you have 1 in the numerator, change it to pi. For example, if you need to convert 450° degrees to pi radians, divide 450/180, you will get 5/2. Now write pi next to 5 in the numerator, and there is your answer. And if you need to convert 30° to pi radians, do the same, you will get 1/6, and just substitute that 1 with pi. The best thing about this method is that it requires no thinking and is extremely fast. I still recommend taking the time to understand how the conversion works, but once you've done that, this method will save you a lot of time, as it works for less common angles just as well.
9:14 breaking 11 into 10+3 and distributing 30 to 10 and 3, 30 x10=100. 30x3=30. 30+300=330°. Just algebra rules but wow you must be a super mathman . I'm jealous as I am learning all of this after high school ! And wish I would have learned sooner but I am glad there is a man like you teaching this on RU-vid thankyou and God bless u!
At 3:00: interesting approach to explain, why there maybe a „unit“ rad. But I wouldn‘t do it. It isn‘t necessary as well. Because the length of the radius isn‘t 6 cm/radius but simply 6 cm. Or you had to insert 12cm/arc as well, which inserts nice explanations to the formula, but likewise is not intended by SI. The units given in SI are m/m, this cancels out. So an angle in radians is a pure number. SI makes it possible to use „rad“ as an „unit“, too. But this I call a reminder-unit, which you can/have to replace by a 1 (that means, ignoring it) to get to the „real“ result. The problem with „rad“ is, that people look at it as „real“ unit, and units you should never loose. But this „unit“ is supposed to be lost, resp. interchanged by a 1.
