Question

Derivative x/(√1-x^2)

Answer 1

Is the function: \(\large \frac{x}{\sqrt{1-x^2}}\) OR is it: \(\large \frac{x}{\sqrt{1}-x^2}\)

Answer 2

The 1st one

Answer 3

quotient rule for this one
\[\left(\frac{f}{g}\right)'=\frac{f'g-g'f}{g^2}\] with
\[f(x)=x,f'(x)=1,g(x)=\sqrt{1-x^2}, g'(x)=\frac{-x}{\sqrt{1-x^2}}\]

Answer 4

Why are you introducing integration and substitution if he is struggling with derivatives?! @SandeepReddy
