For a Cos/Sin graph does every value between 1 and -1 have 4 corresponding angles? two negative and two positive but with the same magnitude? (E.G 270, 90, -270, -90)
And for a Tan graph does every imaginable value (as they are infinitely limited) have 4 angle values?
It makes sense in my head but i just want to make sure! a simple Yes/No would surffice

Its also not true to say that sin(-x) = sin(x) though this is true for cos.
So the solutions may not have the same magnitude.
