Why is sin^1 (sqrt3/2) = pi/3 and cos^1 (sqrt2/2) = 3pi/4 Basically, why in the first problem is the answer a negative reference angle and the second one is not?

Best ResponseYou've already chosen the best response.0the domain for the sin: pi/2 all the way to pi/2 the domain for the cos: 0 all the way to pi

Best ResponseYou've already chosen the best response.0But why is it not 5pi/3?

Best ResponseYou've already chosen the best response.0Th first one is pi/3, isn't that the same as 5pi/3? So why is the reference radian used?

Best ResponseYou've already chosen the best response.05pi/3 is not in the domain of the sin inverse function; but, its equivalent "pi/3" is. So to these inverse a "function" meaning that for every single input there can only be one output, they have to give an answer to a restricted domain.

Best ResponseYou've already chosen the best response.0to keep these inverses a function....is what it was sposed to say

Best ResponseYou've already chosen the best response.0for example: which would you rather have: $20 in as one 20 dollar bill? or in 20 one dollar billls? both are equaivalent amounts, but if all you got is ones, then thats all you get ;)
