For each of the following functions f(t), give the indefinite integral [f(t) dt. a) If f(t) = t, then the indefinite integral ff(t) dt = b) If f(t) =, then the indefinite integral ff(t) dt = c) d) If f(t) = cos(t), then the indefinite integral f f(t) dt = = If f(t)=et, then the indefinite integral f f(t) dt = e) If f(t)=sin(2t), then the indefinite integral f f(t) dt =
