tangent and cotangent


What is the domain of a function?

the set of all permissible inputs


What is the range of a function?

the set of all possible outputs


Why are all trig functions positive in the first quadrant?

because x and y are both positive in the first quadrant


Which two functions are positive in the second quadrant?
