2. Graph of y = sin x Sine graph is periodic (period for y = sin x is ). Five Key Points: Intercepts, Max, and Min. Amplitude = half the distance bet. the max. and min. (amplitude for y = sin x is 1.)

3. Graph of y = cos x Cosine graph is periodic (period for y = cos x is ). Five Key Points: Intercepts, Max, and Min. Amplitude = half the distance bet. the max. and min. (amplitude for y = cos x is 1.)

4. Graphing: Amplitude = Period = Phase Shift : solve equations and This will give you the left and right endpoints of a period. Vertical Shift = The graph of is a reflection in the x-axis of.
