I usually use sin, cos, and tan for testing out graphing libraries, for simple (but complex looking) plots.  I wish these 3 would stay, but I'm not a math person -- can they be easily added back by use of the other functions?

I agree that pow() can go, we do have ^...   how would deg() and rad() be trivially added back?  Anything to do with degrees and radians scar[e]s me.
