This worksheet is great for those beginning to use radians and needing to learn how to find x, y, and r so that next they can use this skill to set up sin, cos, tan, sec, csc, cot ratios with radians. It includes 2 and a half pages for students to write on. The first 2 are representations of all 3 reference angles in all 4 quadrants. The half page is what happens when the terminal side falls on an axis and you need to find x, y, or r to make your ratios and you are unable to draw the reference triangle. This sheet isn't as valuable as the first two and could just be used to project it to the class to discuss it instead of wasting paper and ink to print it. To counteract that, there is a great half page resource that should be utilized to use while learning these skills. It has each of the six ratios and where x, y, and r show up. The rest of the pack are the answers.
There is a lot of difficult typing in this - it took hours to type out. The price is worth it if you need it.
