Edexcel IAL International AS / A Levels Pure Maths 2 (P2) Chapter 6 Trigonometry - Part 2. We review exact values of trigonometrical ratios and trigonometric identities. We also discuss how to solve trigonometric equations such as sin(x) = h, cos(x)=h, tan(x)=h and sin(x+k)=h, cos(x+k)=h, tan(x+k)=h, sin(nx)=h, cos(nx)=h, tan(nx)=h.
