trig functions on a calculator
I have a TI-85 calculator and a computer calculator program called MAPLE. I can't figure out how to do cosecant, secant, and cotangent on either of them. I have tried $\tan^{-1}$, but this would be arctan rather than the reciprocal of tangent, right?

Can't you just type in:
Code:

1 / tan(x)
for cotangent,

Code:

1 / sin(x)
for cosecant,

and
Code:

1 / cos(x)
for secant?
