(-i)^2 = ((-1)^2)(i^2) = 1(-1) = -1 not i.

i remember these questions fro pre-calc
it sucks hardcore, but count your lucky stars your not doing angle identities yet, then double anlge and half angle identities are the worst

what the hell is an angle identity?
I've taken both AP calc classes (5s on both tests) and I'm almost done with my college calc, and I've never heard of angle identities.

google is the best way to explain this
Trigonometric Identities Equations - Trigonometry - EquationSheet
if you have done this then you know what it looks like, trust me (what year are you, im sure you have done it if youve been in college like a year er so, this shit is kinda basic or so they say)

oh! that was back in the APs, I know what you mean. you just memorize em and move on with life. Now triple integrals with conversion to spherical cooridnates, that's a bitch.

waitttt. no it's not.
because a^.5 +b^.5 =/= (a+b)^.5
if we simplify the i^.5 we get
[(2^.5)/2](1+i)
so sqrt that is [(2^.25)/(2^.5)][(1+i)^.5]

At first I was like, oh duh, that's so obvious.
but then the mathy side of my brain took over.
