Understanding the B Value in Trigonometric Functions

The video tutorial explains how to graph trigonometric functions by focusing on the change in the period, determined by the B value. It covers graphing sine, tangent, and cosine functions, detailing how to calculate new periods and label axes. The tutorial also discusses the concept of cycles within a period and provides examples for each function.

What does the B value represent in trigonometric functions?

• The vertical shift of the function

• The coefficient of the angle, affecting the period

• The phase shift of the function

• The amplitude of the function
