This bank consists of 15 multiple choice (bimodal) trig problems. For each trig functions the angles from 0Â° to 330Â° are randomly selected (Problems #1 thru 6). Or the angles from 0 radians to 11Ï€/6 radians (Problems #7 thru 12). The final 3 problems are inverse trig MC problems: arcsin, arccos & arctan. I use these weekly with my AP Calculus class.
