Remark
If the angle is given in degrees, divide the angle by 360 to compute k and use the same formulae given above.
Thus, k = 91
Example
1. Divide |
a|
by 2
p
to get the quotient k (the integral part of the division).
2. Compute the coterminal
b
using the formula
Case II.
(
a
< 0)
Thus, k = 52
Divide
