Graphing a Sine Function by Finding the Amplitude and Period

The video tutorial explains how to find the amplitude and period of a sine function. The teacher begins by introducing the concepts and then delves into the calculation of amplitude using the absolute value of 'a' in the function. The period is calculated using the formula 2π/B, where B is the coefficient of X. The teacher uses examples and graphs to illustrate these concepts, ensuring students understand how to apply them. The session concludes with a brief Q&A.

What is the amplitude of the function a*sin(x)?

• The value of x

• The absolute value of a

• The value of b

• The coefficient of x

If the amplitude of a sine function is 3, what does this indicate about the graph?

• The graph completes one cycle in 3 units

• The graph's maximum and minimum points are 3 units from the x-axis

• The graph's period is 3

• The graph shifts 3 units to the right

What is the formula to calculate the period of a trigonometric function?

• B/π

• π/B

• B/2π

• 2π/B

In the function a*sin(Bx), if B is 2, what is the period of the function?

• 4π

• 2π

• π

• π/2

What does the period of a trigonometric function represent?

• The shift along the x-axis

• The distance between two peaks

• The maximum value of the function

• The time it takes to complete one cycle
