Hello everyone, here's an expression that I am working on. .014*(Int(r^2*Li[3/2](-exp(x-a(r)))), r = 0 .. 2)) which should be equal to a positive number say 1, where a(r) is a always negative and x can be any real number (positive or negative). I am writing Li[3/2](-exp(x-a(r))) equal to polylog(3/2,-exp(x-a(r)). Whatever values I plug in for x and a(r), the left hand side of my equation is always negative. But it should be a positive number. Would someone mind helping me out with this. Jeremy
