Go on :
calc101 dot com
When page be open click option :
derivatives
When page be open type your function and clik option :
DO IT
You will see solution stepbystep
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)
