Students learn how to visualise and sketch the Sine, Cosine and Tangent graphs. They use these graphs to find all the solutions to trigonometric equations. Learning progresses from this to finding the exact solutions to Sine, Cos and Tan of 30, 45, 60 and 90 using an equilateral and right-angled triangle.
This unit takes place in Term 2 of Year 11 and follows on from trigonometry in non-right-angled triangles.
