Okay so here is the problem. Solve arctan7 + arctan8 and solve it so that you only have one arctan in the final sum. I know how to solve regular arctan but when you add them together it gets tricky. Im stuck here and dont really know what to go. Appreciate all the help I can get and please do explain detailed so that I can understand what you are trying to show me. Thanks beforehand
