Maple 9.5 can't recognize exp(+I*phi) = cos(phi) + I*sin(phi)

  1. Jul 13, 2010 #1
    1. The problem statement, all variables and given/known data

    ((1/2)*sin(theta)*cos(phi) - I*(1/2)*sin(theta)*sin(phi))*exp(+I*phi)

    should equal:


    ((1/2)*sin(theta)*cos(phi) + I*(1/2)*sin(theta)*sin(phi))*exp(+I*phi)

    should equal:

    I may add: Maple 9.5 cannot make the simplification:
    exp(-I*phi)*exp(-I*phi) = exp(-2*I*phi);

    ...I'm trying to automate Maple recognizing this: use simplify(,trig) and simplify(,size). There does not seem to be a simplify(,euler) or simplify(,complex), where one can teach Maple to recognize that cancellation. It would make my life tons easier if there was a way to do that. It must exist...somewhere?
