assume (t>0);
integrate(cos(x)*sin(x),x,0, t);

OK this works but it seems like a long way around for beginning students.
My real problem was to get Maxima to show all the intermediate steps in
calculating an answer to a question.
Other people have brought this up in the past and I am not asking that
it be visited again, I am just explaining why I am doing all this.
