inverse function command

[DrD]

There is a tendency to move away from the idea of keypress technology. In time, other methods, including a biological interface, may become practical. Regardless of the technology in place as of a certain time, the idea of information processing using advanced technology is worthwhile.

Using a shopping cart, is better than carrying many items by hand, to the check out stand, possibly needing to go back for more. Hand carrying those items helps to assure ones memory where each product is within the store, but getting in and out of the store faster, is more efficient and results in greater sales volume.

There is a parallel in information technology. It's also inevitable at this point, isn't it? Students already have an option of stay at home (on line) education. That wasn't an option during my experience. Technology is pervasive in the classroom, including devices like the smartphone, and problem solving by example, is more visually and conceptually understandable, using multimedia. I don't see much argument against the idea. Keypress limitations, (as you describe) are but a mere moment on the scholastic timeline.

I agree that the solve command isn't ideal. In fact, the whole idea of calling inverse functions, inverses, is pretty lame. I mean if f(x) is a valid function, calling it's inverse f^-1(x), is just crazy, there is no mathematic recipropral in play there, (no exponent of -1, by the laws of exponents). That's what we call it, and in any event, it would be helpful to have a built in command to accommodate deriving so-called inverse functions.
