I love your quizzes @drcaberry because they're not too hard for me 😊 (usually)

@katzenschiff yayyyy I try to keep them that way.

If sin(x)=–0.2. If x and y are complementary, what is cos(y)?

The radians is a typo. SORRRYYY!!!!

@drcaberry ok, now that this has ended and it's not spoilers, can I nitpick? :) 7π/4 is an equivalent angle if you're not actually moving anything, but a 7π/4 rotation is getting there in the other direction than if you rotate -45⁰! (might matter if you're, say, controlling a robot arm and you don't want it to go the long way)

@joshg It absolutely matters! Thanks for sharing. I was thinking more mathy than a physical device but you are correct.

@drcaberry (this is entirely a nitpick for the benefit of any of your students, not for you since I'm sure you know this) 😂

@joshg Thank you! No worries!!!
