I'm not sure if I've completely misinterpreted what you meant, if you were asking about how to do a specific question using the calculator, can you provide a few example questions (e.g. graphing the arctan function and what not). Anyway:

The inverse trig functions: $\arctan$ , $\arccos$ and $\arcsin$ are often written as: $tan^{-1}$ , $cos^{-1}$ and $sin^{-1}$

The actual button for it on the Nspire (the grey one), is Ctrl + tan, Ctrl + sin etc. I'm not too sure about the newer models, I believe they're accessible using the 'trig' button and in that menu that comes up.
