Odd omission on two calcs

[Matt Agajanian]

Hi all,

Unless I'm mistaken, both the Casio fx-115es and Sharp EL-W516X are missing a Degrees<>Radians conversion pair of functions.

So, I guess we need to use the old routine from SR-50 days:

x [sin] (switch angular mode) [sin^-1].

Hmm. it's a peculiar conversion/function omission on Sharp and Casio's part to say the least.
