Question

help me find the frequency of d = 2 sin ((pi/3)t)!!

Answer 1

What's the period of that trig equation?

Answer 2

ummm... i struggle with periods as well .-.

Answer 3

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

is the general equation

with period

T = 2pi/B

Answer 4

In this case, B = pi/3

Answer 5

T = ??

Answer 6

2pi/(pi/3)?

Answer 7

so..six?

Answer 8

T = 6, yep

Answer 9

The frequency f is found by this formula

f = 1/T

Answer 10

so the answer is 1/6?

Answer 11

correct

Answer 12

thanks a ton! a lot of stuff just cleared up!

Answer 13

I'm glad it has

Answer 14

sooo, for d = 9 cos ((pi/2)t), would the period be 4? @jim_thompson5910

Answer 15

good

Answer 16

thanks :)
