Why is it when I integrate expressions like cos(3*x)^5*sin(3*x)^2, I get this answers in the worksheet mode :

-(1/21)*cos(3*x)^6*sin(3*x)+(1/105)*cos(3*x)^4*sin(3*x)+(4/315)*cos(3*x)^2*sin(3*x)+(8/315)*sin(3*x)

while using the Integration tutor I get:

(1/9)*sin(3*x)^3-(2/15)*sin(3*x)^5+(1/21)*sin(3*x)^7

I know they must be equivalent but it would be nice to have some concistency and also to know how Maple got the first answer.

Anyone has a clue ?

Thanks!
