Is it ever possible for the sine and cosine ratios to be equal to each other?
Yes! If the two shorter sides are equal, so are sine and cosine!
500
What is
sin^-1(sin(60))
equal to?
60 degrees. arcsin and sin are inverses, so they undo each other.
500
What trig function would you use to solve this problem?
None! We don't know it's a right angle, so sin, cos, and tan don't apply.
