[tex]\int_{-\infty}^{\infty} \sin {( 2 \pi y )} \cdot e^{- \frac{(x-y)^2}{4 \nu t}} dy[/tex]

x is between 0 and 1.

[itex]\nu[/itex] is a positive constant.

t is positive.

2. Relevant equations

3. The attempt at a solution

I tried substituting one variable for x-y, and integration by parts. So far, I've gotten nowhere. Can someone tell me which direction to go?

Thanks.

Edit: Also tried considering the Gaussian integral. But when I change the integration variable to get [itex]e^{u^2}[/itex], there's also a Sin term present. I tried to use integration by parts to get rid of that, but couldn't.
