Here we have a very simple problem in derivation but I would not do you any favors by walking you through it. Alas, we cannot incorporate math functions on this word processor.
Let us try a simple download that will make you think your way through this simple problem. I will say that you have an egregious asymptote but I believe you will see where it is and solve the problem.
