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

OpenStudy (cwrw238):

what is the maximum value of the sine function?

OpenStudy (anonymous):

one on the y axis

OpenStudy (cwrw238):

ok so maximum displacement from equilibrium is 2 * 1

OpenStudy (anonymous):

2! Oh wow, I feel dumb

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (cwrw238):

what is the maximum value of the cosine ?

OpenStudy (anonymous):

one again, so this is 9?

OpenStudy (cwrw238):

yep
