Question

what is the phase shift of the function

y=1/2sin(x/3-pi)

Answer 1

@jim_thompson5910

Answer 2

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

has a phase shift of

w = C/B

Answer 3

1/2?

Answer 4

B = ???
C = ??

Answer 5

B=x/3
C=-pi

Answer 6

no B = 1/3 and C = pi

Answer 7

right

Answer 8

so what do you get

Answer 9

pi?

Answer 10

no

Answer 11

w = C/B

w = pi/(1/3)

w = ???

Answer 12

pi/3

Answer 13

no

Answer 14

try again

Answer 15

-pi?

Answer 16

i multiply by 3/1 right?

Answer 17

w = pi/(1/3)

w = (pi/1)/(1/3)

w = (pi/1)*(3/1)

w = ???

Answer 18

3pi?

Answer 19

good

Answer 20

you see i had that originally, but I'm confused about it because its not one of the choices

Answer 21

what are your choices

Answer 22

-pi, 1/2, pi, pi/3

Answer 23

are you sure that they don't want the amplitude?

Answer 24

positve, they don't want the amplitude they want the phase shift

Answer 25

hmm well the closest thing I can think of is pi since C = pi, but the phase shift usually involves B

Answer 26

I guess ill just ask my teacher about it tomorrow, thank you for your effort though, much appreciated!

Answer 27

you're welcome
