find the intergral 5cosx+4sinX Not sure how to do these but I know with 2x-3x^2 = x^2-x^3+c not sure if there done the same way.

This $\displaystyle \int {\left( {5\cos x + 4\sin x} \right)dx}$ ?? Or $\displaystyle \int {\left( {{{\cos }^5}x + {{\sin }^4}x} \right)dx}$ ??
$\displaystyle \int {\left( {5\cos x + 4\sin x} \right)dx}$ Ok I got it 5sinx-4cosx+c
