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

    Asin(Bx - C) phase shift = C/B

    yes you're right ! for, Asin(Bx + C) phase shift = -C/B

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

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

    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)
