Inverse Trigonometric Functions, part 2 of 2

President Barack ObaMATH returns for part 2 of his lesson on Inverse Trigonometric Functions. Part 1 was a thorough intro, and now part 2 dives into more examples to cover the concept fully. We previously covered inverse sin meaning arcsin, etc., and that we have to know the difference between trig with angles and inverse trig with ratios. We go deeper here, involving the unit circle and uncovering some obscure cases. Step into the Oval Office with us, YAY MATH!
