inverse function command

[DrD]

I do want something simpler than that. There is a lot of use for inverse functions in math education. This, alone, should justify having a dedicated command that simply takes a function and returns it's inverse function. We have commands on the prime that are far less commonly used, and one command that seems to indicate that it WOULD be useful for inverse functions (according to the help docs), but isn't.

The solve command has many discussions in the forum, and has been frustrating. It takes additional presence of forethought to relate the idea of obtaining an inverse function, by using a solver.

So yes, a new command, perhaps invf(Func), would be useful, especially for students learning calculus. I would envision such a command to also return a simplified result. This would allow students to quickly confirm intermediate results and verify problem solution progress.

I could create a program for this, which would be contrary to one of the benefits of purchasing a powerful hand held calculator designed for students and educators. Ideally, as I encounter math problems, I want a device with an easy to understand, fully capable interface, that is up to the tasks required. That is where the value is for me, as a calculator customer. It's more than just the pride of ownership, I want the utility value.
