Proving Complex Integrals with Griffiths's Solution Book

[intervoxel]

Homework Statement

On Griffiths's solution book, he concludes that

\int \frac{d}{dx}(\Psi^{*}\frac{d\Psi}{dx})dx = 0

and

\int \frac{d}{dx}(\Psi\Psi^*)dx = 0

How to prove that?

Homework Equations

The Attempt at a Solution

derivative of even function is an odd function and vice-versa. How can this help?
