Hi Mike, I guess when you say integer you mean integral. Your problem comes from the fact that the mathematica function to calculate the sin function is Sin[]. Built in mathematica functions begin with a capital letter and I suspect that you typed a lower case 's'. Integrate[2 x Sin[(n Pi x)/L] Sin[(m Pi x)/L],x ] Should achieve the result you want. Matt
