Question

This is just a quick question. Explain how to do the chain rule form one.

Answer 1

just use it!

Answer 2

(f(g(x)))' = f'(g(x)) * g'(x)

Answer 3

what means "form one"?

Answer 4

Yes I know that is the formula but when it comes to a problem my mind gets so confused

Answer 5

The chain rule has 2 forms.

Answer 6

\[\frac{d}{dx}[\sin(x^3)]=\cos(x^3)\times 3x^2\] is an example

Answer 7

in my college we don't use trig

Answer 8

\[(f\circ g)'=f'\circ g\times g'\] is one way to write it
\[\frac{dy}{dx}=\frac{dy}{du}\times \frac{du}{dx}\] is another

Answer 9

ok without trig
\[\frac{d}{dx}[(x^2+7x)^8=8(x^2+7x)^7\times (2x+7)\]
