I'm completly lost here trying to graph a trig function on my ti-nspire cx cas calculator. I'm asked to graph:


t(θ) = 75/13 - 25/13cot(θ) + 25/6csc(θ)

where 0≤t≤20 and 0º≤0≤90º

I have searched the web and there are a few tutorials on how to do this, but they only explain how to graph the most basic trig functions. Does anybody know how to do this?

First rewrite your function in terms of the basic trig functions the calculator knows. – Henning Makholm Sep 24 '12 at 15:15

Hint: Recall that $\cot(\theta) = \frac{1}{\tan(\theta)}$ and $\csc(\theta) = \frac{1}{\sin(\theta)}$. Can you take it from there?
