Today JPaul and I began a new lesson on Trigonometric Ratios. This is a topic JPaul and I previously discussed in Algebra 2 this past summer, so he had a decent understanding already. We discussed all 6 trig functions. We used the acronym SOHCAHTOA to help us set up the sides. When all 3 side lengths weren't given, we used the Pythagorean Theorem to find the third side. We reviewed the skills needed to simplify correctly, like rationalizing.
