okay i need to find the derivative of


f(x)=cosπ(x^2)


and if you could show steps it would be GREATLY appreciated. thank you so much!

  • calculus - ,

    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 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]

  • calculus - ,

    I read that as
    y = cos (πx^2)

    dy/dx = - sin(πx^2) (2πx)
    = -2πx sin(πx^2)
