What is derivative of $sec^{-1} x^2$?
$Sec^{-1} u$ derivative formulas:
$frac{d}{dx}sec^{-1} u=frac{1}{|u|.sqrt{u^2-1}}.frac{du}{dx}$
Now let’s answer our question.
Differentiate $y=sec^{-1} x^2$
Solution For $x^2$ > 1 > 0,
>>> $frac{dy}{dx}=frac{1}{|x|sqrt{(x^2)^2-1}}.frac{d}{dx}x^2$
>>> $=frac{2x}{x^2sqrt{x^4-1}}=frac{2}{x.sqrt{x^4-1}}$
Answer = $frac{2}{x.sqrt{x^4-1}}$
