Hi guys, I'm doing chain rule problems to practice for exam: I've encountered: y = (e^u - e^-u)/(e^u + e^-u) I've gotten: dy/du = 4/(e^u + e^-u)^2 Is this the correct simplified answer? Thanks for the look!

Thanks for the look! Be sure you understand the following algebraic simplifications: , and deriving now this is much simpler: . Check now that this is just what you got...
