arctan x. The domain of y = tan-1x is and the range is . It helps to think of the range of y = tan-1x as being along the right-hand side of the unit circle (minus the top and bottom points), which is traced out as angles range from (noninclusive). 2. Find the exact value of the expression without a calculator.

This is done by adding 180( to the value of arctan. Example: Find the length and direction of the vector A= . Solution: || A || = = = 10; arctan = arctan(-1) = -45(. Since the terminal point of A is in quandrant II, we must add 180( to this value to obtain ( = 135(.
