Use fundamental identities to write the first expression in terms of the second, if 0 < t < π/2
sec t, sin t
cos t, cot t
------------------------------------------------------

1.  sec(t) = 1%2Fcos%28t%29 = 1%2Fsqrt%281-sin%5E2%28t%29%29.


2.  cos(t) = 1%2F%281+%2B+%281%2Fcot%5E2%28t%29%29%29%29.
