The Clockwork Crypt

Before the debrief: three questions

Same concepts as your pre-check, new questions.

What is the period of y = cos(x/3)?

2π/33π/36π

Which equation swings twice as high as y = sin(x)?

y = sin(x) + 2y = 2sin(x)y = sin(2x)y = sin(x/2)

Which angle is a quarter turn?

π/22ππ/4π

Turn your notes into a game where the concept is the rules.
