I was just wondering how it picks U and V, because if it picked it the
other way around then then it would give sin^2(x)/2 as the answer.
I also tried
integrate(cos(n*x)*sin(n*x),x,0, t)
but this doesn't give an answer. Does Maxima know how to do the definite
integral from zero to t ?
By the way I am using
http://www.my-tool.com/mathematics/maximaphp/
I do this because I can use it from any lecture room without having
Maxima installed .
