unfortunately... very unfortunately, I entered it correctly.

I need the integral of sin(x^3)

any pointers?

I have to find this because ultimately I need the definite integral (1 on top and t on the bottom) and then I have to find the derivative of this.

so, F(t) = (1 on top, x on bottom of integral sign) of sin(x^3) dx

Find F'(x)

I tried jumping around the integrating just to find the derivative part and entered: sin(1) - sin(x^3) but it wasn't correct. I was hoping it was a shortcut.
