Trigonometric identities and equations

This resource contains 6 PowerPoint presentations to support the delivery of chapter 6 trigonometric identities and equations, International A level Pure mathematics 2, Pearson.
The presentations cover the following Learning Objectives:

• Calculate the sine, cosine and tangent of any angle.
• Know the exact trigonometric ratios for 30°,45° & 60°.
• Know and use the relationships tan⁡ θ≡ sin⁡θ/cos⁡θ and sin^2⁡ θ+cos^2⁡ θ ≡1 .
• Solve trigonometric equations of the forms sin⁡ θ=k ,cos⁡ θ=k ,tan⁡ θ=k
• Solve more complicated equations of the forms sin⁡ nθ=k and sin⁡(θ±α)=k and equivalent equations involving cos and tan.
• Solve trigonometric equations that produce quadratics.
