Homework Statement



I have the integral:
[itex]\int^{\infty}_{-\infty}ie^{-(x-x_{0})^{2}}sin(vx) dx[/itex]

where x_0 and v are real constants.

The sine function is odd. But what about the exponential? If it's even, then the integral is zero, but the exponential is not centred around origo. Will the integral still be zero as long as the exponential is not an odd function?

hi atlantic! :smile:

no

try using sin(vx) = sin(v(x - xo))cos(vxo) + cos(v(x - xo))sin(vxo) :wink:

The first thing I would do is to let [itex]x=\pm a[/itex] and compare the two, what would you expect to happen if the function was odd?
