There are no cosecant (csc), secant (sec), or cotangent (cot) commands.
Add the cosecant (csc), secant (sec), and cotangent (cot) commands to the toolbox.
The problem with these is that they're inverse functions. Inverse functions require a dedicated CAS.
Inverse functions require a dedicated CAS.
The Nspire CX (non-cas) has this feature. Isn't it just scs(x) = 1/sin(x)?
@0b101 is right: I think there is not much work to do, except creating a dedicated menu in the Toolbox and defining these three new functions as inverse of there counterparts. Just look at what is already feasible with the current version of Epsilon:


Is anyone able to weigh in on whether a PR for this would be accepted?
Any updates on this? I might be able to take a crack at a pull request if there are no objections. Not sure who to ask, @Ecco?
