I got some expression but do not know how to get the simplest form by using simplify > C := -(1/2)*exp(-I*omega0*t)+(1/2)*exp((-beta-I*omega0-I*alpha)*t); > Csq := evalc(conjugate(C)*C); > simplify(Csq); -(1/2)*cos(omega0*t)*exp(-t*beta)*cos(omega0*t+t*alpha)+1/4-(1/2)*sin(omega0*t)*exp(-t*beta)*sin(omega0*t+t*alpha)+(1/4)*exp(-2*t*beta) which obviously should be equal to 1/4*(1+exp(-2*t*beta)-2*exp(-t*beta)*cos(t*alpha)). How can I get this form using Maple?
