amplitude = -4; period = 2π; phase shift: x = -PI/2 amplitude = -4; period = π; phase shift: x = PI/2 amplitude = 4; period = π; phase shift: x = -PI/2 amplitude = 4; period = 2π; phase shift: x = PI/2

is period 2

i mean pi

which one? 2 or pi?

a=4 p=pi shift=pi/2

pi lol

`a=4 p=pi shift=pi/2` is correct

yayayay youre the best omg
jim_thompson5910
  • jim_thompson5910
actually the phase shift should be negative
jim_thompson5910
  • jim_thompson5910
since 2x + pi turns into 2x - (-pi)

C/B = (-pi)/2 = -pi/2
