What effect does changing a parameter have on the graph of a trigonometric function? Pupils use a Desmos applet to explore the general sine graph. They experiment changing different parameters and record the resulting change of the graph. To round out the lesson, scholars generate a general description of the effects.

Instructional Ideas

• Lead a discussion on whether the parameter changes would do the same for cosine

Classroom Considerations

• Open the Desmos app in the included materials independently
• Use as either a partner or individual activity

Pros

• Includes suggestions on ways to use the task within instruction
• Provides a structured exploration

Cons

• The margins in the PDF cut off part of the text
