Graphing the Sine Function

The video tutorial covers graphing the sine function, focusing on key concepts like amplitude, period, and important points in the graph. It explains how to calculate amplitude and period, and how to identify key points such as maximum, minimum, and intercepts. The tutorial also demonstrates graphing multiple periods and applying vertical shifts to the graph by modifying the function.

How do you determine the increments between important points in a sine function?

• Divide the period by 2

• Multiply the period by 4

• Divide the period by 4

• Add 4 to the period

What does a negative D value indicate in a sine function transformation?
