Question

True or False......There are values of t so that sin t = .6 and cos t = .8

Answer 1

The regions of Cosine and sine are between -1 and 1. Using that knowledge the answer is yes. You can also check this kind of stuff by taking the inverse of the functions and multiplying by the answers. i.e. sin^-1(.6)=t

Answer 2

Ty ax :)

Answer 3

@Mypost1994 By There are values of t so that sin t = .6 and cos t = .8, do you mean a distinct value of t where sin t = .6 AND cos t = .8 for that same distinct value of t?

Or, do you mean that there exists a) a value of t for which sin t =.6; and b) Does there exist a value of t for which cos t = .8?

Just wondering.
