Marco, Is there some dependency of rho on x or is rho supposed to be in the exponent of Sin? As it stands, your integral does not depend on rho which can be taken outside the integral so it is not clear why you were having difficulties. Please make it more clear what problem you are having. regards, RF >>> Marco de Innocentis <mdi11 at hotmail.com> 05/07/00 07:18PM >>> I need to calculate the following integral Integrate [(Sin[x])^2 rho Exp[I n x],{x,0,2 Pi}] as a function of the two parameters rho and n. I have tried it for rho = 1, 4, 8, 10, and it works, but it doesn't work at all for rho = 12. I left the computer on all night but only got the same expression as a result. Any suggestions?
