So now it is in the format ∫u v dx we can proceed: Differentiate u: u' = x' = 1 Integrate v: ∫v dx = ∫cos(x) dx = sin(x) (see Integration Rules) Now we can put it together: Simplify and solve: x sin(x) − ∫sin(x) dx x sin(x) + cos(x) + C Done!So...

This looks quite different from13cos3x−cosx+C. To see that these antiderivatives are equivalent, we can make use of a few trigonometric identities: 112(cos(3x)−9cosx)=112(cos(x+2x)−9cosx)=112(cos(x)cos(2x)−sin(x)sin(2x)−9cosx)...
