The distance that one graph must be shifted to the right or to the left to coincide with another graph is called the phase shift . For y = a sin b(x + c) + d ; y = a cos b(x+c) + d The amplitude is

Unformatted text preview: • The period for sine and cosine function = a 2 b π 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 What would America be called if we all drove pink cars?
