What is the amplitude of y = (3sinx/2) + 4?
Any link of proof would be appreciated if you have one

Thank you

  • trig -

    y = (3sinx/2) + 4

    If you mean
    y = 3 sin (x/2) + 4
    the amplitude is 3
    It goes up from 4 to 7 when the sine is +1 and down from 4 to 1 when the sine function is -1
