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.

A bit confusing (you don't need to set cos t = x)
but yes the basic idea is that cos t = 1 / sec t
So if I have sec t I can get cos t.
Now, if I have cos t I can get sin t (how?)
Now I have both sin t and cos t. Are there
any trig functions that I can't get?

Are you saying that if cos t = 1/ sec t, then sin t would = +- sqrt(1-
(1 / sec t)^2)
with all that being said then I guess you could figure out the other
three functions?
