Homework Statement
I'm trying to do a few problems that ask me to "find the point (x,y) on the unit circle that corresponds to the real number t." Examples of these problems are:
t = pi / 4
t = 7pi / 6
t = 4pi / 3 etc etc

The Attempt at a Solution
I did a search on this board before posting and found a great cheat sheet, but I was still wondering, is there a formula that allows you to find the point? Or do you just have to memorize/reference a cheat sheet for each angle?
