How do you evaluate #tan^-1(-1)# without a calculator?
1 Answer
Depending upon if the domain is restricted to
Explanation:
What you are trying to solve is
Since the problem deals with the inverse tangent, that means we will use the tangent function to solve the problem.
Now let's think about when
If we are rotating an angle and dealing with a right triangle, we know that
Since you are more than likely discussing radians,
Therefore
If the domain is restricted to
