see pi inside sine function

yes..

that's called phase shift

or phase change

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

Asin(Bx - C) phase shift = C/B
anonymous
  • anonymous
wait...istn it -C/B
ganeshie8
  • ganeshie8
yes you're right ! for, Asin(Bx + C) phase shift = -C/B

3sin(x/2 + pi) here B = 1/2, C = pi just plugin :)

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

1/2 / pi?
anonymous
  • anonymous
oh other way around i meant!
ganeshie8
  • ganeshie8
-C/B = -pi/1/2 = -2pi
anonymous
  • anonymous
yes!! thank you!!

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)

.33 i think
