TRIGONOMETRY (GRAPHS OF TRIGONOMETRICAL FUNCTIONS)
Performance Objectives
Student should be able to:
Construct table of values for , plot the graphs of the table of values and interpreting and reading out given values.
Content
Sine and Cosine Graphs
The diagram above shows how the sine and cosine graphs looks like but before we proceed to solving / plotting our graphs, it is important we note a few key points
- All values of sinθ and cosθ lie between +1 and – 1.
- The sine and cosine curves have the same wave shape but they start from different points.
