    If I was taking the derivative of the attached function;

    Is the derivative in 'C'

    dx=(r*b*pow(sin(pi*pow(x,a)),b-1)*cos(pi*pow(x,a))));

    or

    dx=pi*a*b*r*pow(x, a-1)*pow(sin(pi*pow(x,a)),b-1) *cos(pi*pow(x,a));

    Thank you!

    It's possible that the original equation in the attachment could be seen as being ambigious.

    I know the equation in the attachment when written in C is the following;

    r*pow(sin(3.14159265*pow(x,a)),b)

    Does this help identify the "proper" identity of the original equation?

    Have you tried turing it off and on again?

    Obviously that's the first thing I did, but it didn't work for some reason.
