Section 2.4 The distance that one graph must be shifted to th
right or to the left to coincide with another graph i
called the phase shift.
For y = a sin b(x + c) + d ; y = a cos b(x+c) + d
b(x+c) The amplitude is a
The The period is 2π
b The phase shift is c units to the left if c > 0. The phase shift is c units to the right if c < 0. The vertical shift is d units up if d > 0. The vertical shift is d units down if d < 0. Joke Time
