You should have definitions:
sec(x) = 1/cos(x)
csc(x) = 1/sin(x)
cot(x) = 1/tan(x)
What does sec, cot and csc stand for in Trig. When you are trying to find something in degrees and pi wise. Like
sec (30 degrees) * cot (45 degress
sec `pi - csc (`pi/2)
Is there a certain number that sec, cot, and csc stand for like sin, cos, and tan?
