1. The problem statement, all variables and given/known data I'm in an Intermediate Mechanics course right now, and while the Physics itself isn't giving me too much trouble, I am lagging behind in the Math department. I am trying to solve the integral: [tex]\int cos(\omega t) sin(\omega t - \delta) dt[/tex] 2. Relevant equations [tex]sin(A-B) = sin(A)cos(B) - sin(B)cos(A)[/tex] 3. The attempt at a solution The first thing I recognized is that the trig functions had the same argument, plus a value, so I figured I could apply the above equation to the integral. However, that really just made things look more complicated. [tex]\int cos(\omega t)sin(\omega t)cos(\delta) -sin(\delta)cos^2(\omega t) dt[/tex] I stared at this for a while, but I couldn't find any substitutions (Which is what I was expecting.) I then thought that maybe I should try an integral table, to see if this was listed somewhere, but I couldn't find any functions that might have made sense. The added value in the argument of the "Sin" function is what's tripping me up. Can anyone give me a push in the right direction?
