I was asked to integrate( exp(-x) cos(x)) with respect to x with the limits x=0 and x= infinity.(adsbygoogle = window.adsbygoogle || []).push({});

I calculated the indefinite integral to be 0.5 exp(-x) [sin(x)-cos(x)].

I was stuck in the part where we apply limit x approaches infinity of sin(x) and cos x.

Please help me out.

Best,

Saksham
