Trigonometry Reference Values Quiz: sin, cos of 0°, 15°, 30°, 45°, 60°, 75°, 90°
This page is for when you are convinced you need some rote
memorization to learn these reference values. It randomly generates
a 14-question multiple choice quiz over the basic reference values
for sin() and cos(), and then administers the quiz.
How to take a quiz:
At the end of the quiz, the page will pop up a scoring report. I
have decided on a total of fourteen points:
- Click on the "Start Quiz" button.
- For each reference value requested, click on the radio button
to the left of the answer.
- Seven points: cofunction identities. One point for giving the
same answer for each side of a cofunction identity.
- Seven points: the actual answer. One point for giving the
correct answer at least once for each cofunction
Opinions, comments, criticism, etc.? Let me know about it.
