What is the integral of a function: (e^(-x))cos(x/2) dx ??

The answer which I got was  (e^(-x))sin(x/2)-cos(x/2)(e^(-x))  
 
However all the math solvers on the internet are giving different answers. Could you clear things up and tell me a definite answer. I've done many many manipulations to this equation, but the best answer I came up with was this one. 
Thank you.
