Question

For the simple harmonic motion equation d = 2sin(π/3 * t) , what is the maximum displacement from the equilibrium position?

Answer 1

what is the maximum value of the sine function?

Answer 2

one on the y axis

Answer 3

ok so maximum displacement from equilibrium is 2 * 1

Answer 4

2! Oh wow, I feel dumb

Answer 5

so what about the equation d = 9cos(π/2 * t) ?

Answer 6

Well it's very similar to the last one so what do you think?

Answer 7

what is the maximum value of the cosine ?

Answer 8

one again, so this is 9?

Answer 9

yep
