Hello,

how to I integrate something like this?: (I do understand how to integrate something just of $\displaystyle t$, $\displaystyle x$ or some other variable)

$\displaystyle \int_{-\infty}^{\infty}3cos(\omega\tau)1(\tau)1(t-\tau)d\tau$

Can someone give some guidlines? Maybe I will post more questions later, if I will not completly understand.

Thank you.
