+7%2Api%2F4+
--------------
Note that this angle is just +pi%2F4+
short of being +8%2Api%2F4+, which is
+2%2Api+, a completed circle.
------------------------------
So, +7%2Api%2F4+ is in the 4th quadrant, and
makes an angle of +-pi%2F4+ with the
0 radian reference
-----------------------
The tan is negative in the 4th quadrant
+tan%28+-pi%2F4+%29+=+-1+
