Exact Trigonometric Solutions

              Exact Trigonometric Solutions

              Students learn how to solve trigonometrical equations using special triangles.

              As learning progresses they use the properties of trigonometric graphs to find additional solutions beyond 90°.

              Differentiated Learning Objectives
              • All students should be able to calculate the exact values of Sin and Cos 30°, 45°, 60° and 90°.
              • Most students should be able to solve trigonometric equations such as 2Cos45°.
              • Some students should be able to use trigonometric graphs to find alternative solutions to Sin, Cos and Tan 30°, 45°, 60° and 90°
