When page be open click option :

derivatives

When page be open type your function and clik option :

DO IT

You will see solution step-by-step

Remark :

If expresion for f(x) mean :

cos pi* ( x ^ 2 )

type :

cos[pi]*x^2

If expresion for f(x) mean :

cos ( pi * x ^ 2 )

type :

cos[pi*x^2]

I read that as

y = cos (πx^2)

dy/dx = - sin(πx^2) (2πx)

= -2πx sin(πx^2)
