It is a very powerful search engine that will provide with plenty of information on the function, its integral, and even provide steps of how to do the integral!This search engine helped me get through accelerated calculus, and Im sure it will help you too.Best of luck!......
Once multipled out, you get
cos^2x + 2sinxcosx + sin^2x, simplify that you get
2sinxcosx +1
then the anti of that is -
1/2cos2x - x

Is this the right way of doing it?

Yes you are doing it properly, however you have a tiny mistake in the last step. It should be x - (1/2)cos2x , small sign error.

A great place to check your answers would be: wolframalpha.com

just ask exactly what you want in this case "anti-derivative of (cosx+sinx)^2" or "integral (cosx+sinx)^2?"
