Question

For the simple harmonic motion equation d = 5sin(π/4 t) , what is the period?

Answer 1

hint:

the period of y = A*sin(Bx - C) + D

is

T = 2pi/B

Answer 2

Okay so this is what I had got... I had to make sure:

2*π*f*t = π*t/4
f = 1/8
T = 1/f = 8

Answer 3

THANKS!

Answer 4

T = 8 is correct, nice work

Answer 5

Then what about this one?

For the simple harmonic motion equation d = 8sin(4πt) , what is the period?

Answer 6

in this case, B = 4pi

so

T = 2pi/B = ???

Answer 7

Can't be the same! Why does it look like the other one?

Answer 8

the period formula is the same, but the value of B is different this time

Answer 9

1/2 right?

Answer 10

good, the period is 1/2

Answer 11

Thanks! :)

Answer 12

you got the hang of this

Answer 13

you're welcome

Answer 14

yes sir-ee!
