Best ResponseYou've already chosen the best response.0omg i totally forgot we have to restrict the domain of tan so that tan would have inverse and pi is outside that domain

Best ResponseYou've already chosen the best response.0for reals tan is not one to one so we have to make it one to one so it does have a freaking inverse
