You have the most amazing speaking voice, perfect for communicating. Not to mention what a great teacher you are!:)

[ShadowKiller]

Thanks a million. I wished everyone taught it the same way you did.

[andreajames]

you did more for me in 5 minutes than my professor did in four hours worth of class. thanks

4:14 lmao i love how he says "very cool" when he simplifies it to tan(5x)

Ran into this guy by algorithm. Love his clear explanations and soothing voice. Thanks dude! Gonna be watching

Wow I was 10 when you made this video, now I'm 19 now and in first year uni and you helped me!

I'm from algeria it's my 1st time learning math with english teacher :'D thanks

I think that it is important to explain from where the derivative is coming from. Your explanation is clear but not that complete. And it is important to make people understand the WHY. The thing is that for example ln(x^4) is the derivative of the compound. Which means that it obeys at the law of: (f(g(x)))'=f'(g(x))g'(x). And that is WHY we have to apply the equation in that way. f(x)= lnx so f'(x)=1/x and g(x)=x^4 and g'(x)=4x. All you have to do next is to replace the values in the formula.

its crazy how this used to be cutting edge math and now I can learn it here for free

This was absolutely awesome! The way you taught it was much better. Thanks so much.

bro thanks for bridging that gap for me. i was lost trying to understand this concept from work with skipped steps.

[aylinb]

I am german and understood you way better than my own teacher...

[TheZooman]

Awesome. I love these quick and dirty reviews. Great for people  who forget, like me.

[bennyburwell]

thank you so was stuck forever trying to read my teachers notes and this explained it by the time I got to the 1:08 mark

In the first problem for y=ln(3x), you could have also done using properties of logarithms before taking the derivative as y=ln(3)+ln(x). The derivative is the same as from before, which is y’=1/x.

What's the plural of Jesus? I've seen so many of them on YouTube and they've helped me a lot. I have my IGCSE exam in a few hours and this was very helpful.

[malaklove]

ur the best ive never understood the Ln rule before... Thank u so much

[daviddemar]

A very good video-you get a compliment from me (A later in life mathlete). One small nitpick though-i think it would have helped some of your less experienced viewers if you had mentioned once or twice that in your examples the natural log function is the "outside" function for chain rule purposes

[thomyhr]

This video is great! 5 minutes of this and now I understand it perfectly! Thank you! :D

[emylolita]

Thanks a lot sir, that was very helpful,
I got a question, which grade this lesosn made for?
