The math problem:
Express each of the other trigonometric functions of t in terms of sec
t.

Can this be done with csc t and sin t since they do not contain x (ie
cos t = x therefore one can determine cos t in terms of sec t because
sec t = 1/x).

Thanks for all your help.

cos(t) = 1 / sec(t)

You also know that

sin^2(t) + cos^2(t) = 1

csc(t) = 1 / sin(t)

tan(t) = 1 / cot(t) = sin(t) / cos(t)
