# Thread: Integrating exponential and sine function

1. ## Integrating exponential and sine function

Hey guys,

Just having a bit of a mental blank. How do I integrate a function f(x) = e^x * sin(x)

I know there is something you have to do with integration by parts where you do it twice then sub back a previous result. Does anyone have an example?
