Question

Chain rule help? Can anyone give examples of finding the derivative using the chain rule...

Answer 1

find the derivative of
\[\sqrt{1-x^2}\]

Answer 2

or try this, first find the derivative of
\[\frac{1-x}{1+x}\] and then use the chain rule to find the derivative of
\[\frac{1-\sin(x)}{1+\sin(x)}\]

Answer 3

Honestly, I have no idea how to do that.. Do you have to use the quotient rule first?
Since this problem involves division?
