Goal #1 I understand that the trig functions (sin, cos, tan) have inverse functions called: sin-1 cos-1 tan-1
    (some mathematicians use the words arcsin, arccos, and arctan instead of the notation you see above, but the notation above is much more common and that is what we will use) Goal #2 I understand that trig functions take in an angle and output a ratio of side lengths. I understand that inverse trig functions take in a ratio of side lengths and output an angle. Goal #3 Given a right triangle, I can use inverse trig functions to find a missing angle measure.
