I am trying to create an activity for evaluating trig ratios with the unit circle. I want students to type in an answer like sqrt(3)/2 with a math input and have them see if they have the correct answer. I would also like them to be able to get the correct answer for inverse trig ratios where they would use a math type to get pi in their answer.

I have attached where I have made it to with the activity, but the only way I could get it to work is having students type in the decimal approximation. My programming skills are minimal and I am just trying to work through it with examples I have found on the internet to mimic. Any help would be appreciated!
