# Limit of an integral

## Homework Statement

$$lim n \rightarrow\inf \int sin(pi*x^{n})dx$$
...integral is from x=0 to 1/2.

## The Attempt at a Solution

Lebesgue's Dominated Convergence Theorem says that I can move the limit inside, but only if fn converges pointwise to a limit f, which I don't believe it does. Even so, there is no limit as n approaches infinity of fn.
I also tried u substitution, setting u = pi*x^n, but that didn't get me anywhere.
