the spotlight calculator is a great idea, but so far, it seems to only be able to do the 4 basic functions +-/* as well as using parentheses (eg (4/5)+(2*7)) am i missing something, or can it do more? i tried to use ^ to do exponents, but that doesn't work. also trigonometric functions don't work... sin cos tan i really just need exponents and trig. oh, and maybe log and e^ ?? is there a list of commands for it somewhere, or is it just meant to be a basic 4 function calculator? and in that case, is there any way i can get a more functional calc that i can type into instead of clicking buttons?
