Re: [Maxima-discuss] how to get sec, csc, cot instead of reciprocals of cos, sin, tan

In general there is a tension between finding the smallest conventional representation, and ease of manipulation -- where you would prefer to have the fewest number of essentially interchangeable functions hanging around. People are usually happy with sin and cos. Even tan is an extra since sin/cos is already there. Sometimes people would prefer sec. thought: how would you prefer to represent sec, cot, etc if you were writing a program to do symbolic integration?
