Graphing the Sine Graph

The video tutorial covers the basics of graphing sine and cosine functions, focusing on amplitude, period, and reflection. It explains how to calculate the amplitude and period, and how to divide the period into equal parts for graphing. The tutorial also demonstrates how to continue the graph using key points and discusses the impact of reflection on the graph's direction.

What does the amplitude of a graph represent?

• The horizontal shift of the graph

• The vertical distance from the X-axis

• The number of cycles in the graph

• The reflection point of the graph

How does a negative amplitude affect the graph?

• It causes a reflection about the X-axis

• It causes a reflection about the Y-axis

• It increases the period of the graph

• It shifts the graph to the right

What is the formula to find the period of a sine or cosine graph?

• π/A

• 2π/B

• 2π/A

• π/B

How many important points are there in one period of a sine or cosine graph?

• 5

• 4

• 3

• 2

What is the distance between each important point in the graph?

• π/3

• π/12

• π/4

• π/6

What happens to the graph after completing one cycle?

• It stops

• It doubles in size

• It reverses direction

• It repeats itself

How can you extend the graph in the negative direction?

• By adding π/6

• By adding π/12

• By subtracting π/12

• By subtracting π/6
