**Graphing Sine and Cosine with Phase (Horizontal) Shifts**

How to find the phase shift (the horizontal shift) of a couple of trig functions?

Example:

What is the phase shift for each of the following functions?

1. y = cos(x - 4)

2. y = sin [2(x + 1)]

3. y = cos (10x + 30)
**Graphing Sine and Cosine with Phase (Horizontal) Shifts**

How to graph a trigonometric function by graphing the original and then applying the phase shift?

Example:

Which graph most closely resembles the graph of y = -2 sin (x - π)

**Trigonometric Functions and Graphing: Amplitude, Period, Vertical and Horizontal Shifts**

How to find the amplitude, period, vertical and horizontal shifts for a trig function and use that to graph the function.

Example:

Graph y = 2 cos(x - π/2) + 1
