What is the general form of a sine function?

Back

The general form is y = a sin(bx + c) + d, where a is the amplitude, b affects the period, c is the phase shift, and d is the vertical shift.

What is the general form of a cosine function?

Back

The general form is y = a cos(bx + c) + d, where a is the amplitude, b affects the period, c is the phase shift, and d is the vertical shift.

What happens to the graph of y = sin(x) when the amplitude is increased?

Back

Increasing the amplitude stretches the graph vertically, making the peaks and troughs further from the midline.
