Asked by Sarah

Could someone help me calculate the integral:
a = 0 b = pi^(-3/2)
x*sin(x^3)dx

This one cannot be done using elementary functions. You will have to use some numerical method.

Now, if you had said x^2 sin(x^3) dx then that would just have been sin(u) du, which is easy.

I bet it was indeed x^2 sin(x^3) dx

yeah, and I don't like that 1/√π<sup><sup>3</sup></sup> as a limit, either
More like ∛(π/2)
