I have the trigonometric equations:

y=3+2sec(pi/8)(x-3)

y=12+4cot(pi/6)(x-1)

y=3+7csc(pi/4)(x-1)

how do I make these into sine, cosine, and tangent equations so that I can work with them more easily?

Is the last parentheses part of the angle?
for example, do you mean

y=3+2sec[(pi/8)(x-3)] ?

If not, just substitute 1.0824 for sec pi/8 etc.
