Question

HELP what is the phase shift of 3sin(x/2 + pi)

Answer 1

pi

Answer 2

I guess

Answer 3

how did you get that??

Answer 4

see pi inside sine function

Answer 5

yes..

Answer 6

that's called phase shift

Answer 7

or phase change

Answer 8

the phase shift...isnt its -c/b so wouldnt it be -pi/1??

Answer 9

Asin(Bx - C)

phase shift = C/B

Answer 10

wait...istn it -C/B

Answer 11

yes you're right !

for,
Asin(Bx + C)

phase shift = -C/B

Answer 12

3sin(x/2 + pi)

here B = 1/2, C = pi

just plugin :)

Answer 13

okay so since its 3sin(x/2 + pi)

Answer 14

1/2 / pi?

Answer 15

oh other way around i meant!

Answer 16

-C/B = -pi/1/2 = -2pi

Answer 17

yes!! thank you!!

Answer 18

np..

just remember that, since coefficient of x is a fraction, here, its period is more. and hence phase difference also will be more than the the constant term(pi here)

Answer 19

.33 i think
