Tues 12th Mar - How to use Trig graphs to work out sin,cos and Tan values greater than 90 and less than 0 and Transforming Trig Graphs

LEARNING OBJECTIVE: Discover how to use trig graphs to work out values of sin/cos/tan greater than 90 and less than 0. Also look at the results of transforming trig graphs.

SUCCESS CRITERIA: You will be able to find the sin/cos/tan of any angle, and use the graphs to find trig identities. You will also be able to sketch a trig graph after it has been transformed.

LESSON: USe theses Lesson to show how to use trig graphs to aid finding trig values.

Sin and Cosine Graphs
