He lost me in the factoring.

I've been watching these videos lately and realized that your voice sounds like J.K. Simmons.

You're awesome!! Way better than my maths teacher!! You just made it all easy to understand! Which video should be watched after this one?

Please do a video on trigonometry, analytic geometry and solid geometry also thank you. these videos helped me a lot :)

You sir, a fucking legend.

As I get further into calc, I realize my problems have really been algebra related -___-....derivatives are sort of easy compared to simplifying long polynomials, in my opinion.

You should have a chain rule 4 video, where you do some problems of multiple chains.

This is the best calculus instruction I've ever had (every time I come back to calculus, it's to learn that the chain rule has already slipped my @#$%&! mind)

Is there a button so I can like all of your videos at once? :)

It wasn't clear in 2:54

7 people failed calculus
frisbeedude1121 (6 years ago)
the main point is that he factors in his head
frisbeedude1121 (6 years ago)
What he did is at 2:01 he factors out an (x^3 + 5x)^9 because you get it in two of the expressions. he also factors out a 2 from the 10 in the beginning and the 2x in the end. he ALSO factors out an x from the x^2 in the very beginning and an x from the 2x in the end. so all of this is done mentally. so after all that he has an 2x(x^3 + 5x)^9 (which are what he factored out), time the rest, which is x5(3x^2 + 5) + (x^3 + 5x). sorry, a confusing and possibly impossible to understand answer, but

at 2:20 , how did he get a 5x?
margie berdin (6 years ago)
yeah right...i fall inlove in math because of him...lol
JOHNNY AYE (6 years ago)
im in honors algebra 2 and im learning calculus. that proves that this guy is good at teaching, this guy should get teacher of the U.S award!

what is the derivative of youtube?
BodieSkate (8 years ago)
I have literally been doing these for 12 hours straight and this is by far the clearest I have seen it presented. Thanks.
Laura Campbell (8 years ago)
Come to Australia and lecture maths at UQ? Thanks man, you are amazing. Thankyou for being so patient and saving my mathematical ass. :)

Lo mejor q me pudo pasar, son estos videos!!
popedarren (8 years ago)
I wish I had youtube in college. This is wicked. Great examples, a well spoken professor and not a million questions from people who have no business being in the class. It's rejuvenated my love for math... much to the dismay of my wife. lol

DR. Youtube is awesome lol

no he didn't... the 5x is in the brackets. He just took the 2x out completely

its the derivitave of the frist x(square) = 2x

Awesome Videos, Explains things very well. I use his videos to supplement what i learn in my class, very helpful...
Zekian (9 years ago)
Because product rule states d/dx(UV) = V(du/dx) + U(dv/dx) or written better as VU' + UV'
thedarkisonfire (9 years ago)
omg thanks your pretty good, this ones were the only ones that i couldnt understand!
johnpeter murekezi (9 years ago)

Thank you so much! My teacher at school cannot teach at all! I finally understand how to do questions similar to the first example now.

kyle ksmooth (10 years ago)
can anybody get this one? i've been stuck on it for at least 45 minutes x(2-x^2)^1/2 the answer in my book is (2-2x^2)/(2-x^2)^1/2 and I havn't been able to get it yet
Rosanella di-Costanzo (10 years ago)
Thank you for your excellent lecture. The Chain Rule has been driving me bonkers, but I think I'm beginning to see where the 'outside' and the 'inside' functions are to calculate the lot. I'm still struggling a bit with functions that have e or ln involved. I guess I'll get there in the end. Rosanella :-)

If you leave (x+3) in the denominator, the exponent will be 3/2. It all depends on whether you want positive exponents only, or not.

You are the best. thank you
