Trigonometric Exact Values
The below QuickQuestion Interface © generates random questions on finding exact trigonometric values.
Choose the unit of the angles, and the range of sizes for the angles you would like to appear.
Decide which trig functions you want to work with, the wording of the question, and which notation you want to use for the inverse function.
Use the buttons to create random questions and show the answers.
There is a 10QQI version of this activity.

Ideas for Teachers
The QQI activities are a great way to get all students working. Put random questions on the board, and then get students to answer them on mini-whiteboards. Once all students have answered, and held up their solutions (with working), reveal the answer to see if they were right. Discuss any misconceptions from the working they have shown, or if they have all got it correct, move on to another question (changing the options to make if more difficult if necessary).
