Trigonometric Equations Using Identities

fx-CG50 A-Level IB

The activity provides practice in sorting trigonometric equations where more than one function is used together and then matching each with the subsequent lines of working in the algebraic solution of the trig equations. Students are required to use the identities for tan x = sin x /cos x and sin2 x + cos2 x = 1. Learners use their calculators at the final step to find the solutions of the basic trigonometric equations in their solution.
