Here I offer a complete Lesson on Maths A level suitable to Edexcel C2 Trigonometry(Trigonometrical Identities and Simple Equations). This set of notes completely covers the chapter with 52 worked examples. With over 20 years experience in teaching O level and A level Mathematics (Pure Mathematics and Mechanics ) I offer this notes covering a wide range of problems with complete solutions. In this way I hope to help students achieve a high score in their A level Maths examination. Each Lesson covers theory and formula necessary for the chapter, and step by step explanation of all solutions.Problems are arranged in an ascending order of difficulty reaching A level standard. The aim is to show students as many worked examples as possible which is not practical to see in class or with a personal tutor. Applies also for any students studying at this level. It includes: 1) Simple trigonometric formula: a) tanx=sinx/cosx b) sin DEGREES2(x)+cos DEGREES2(x)=1 2) Proving Identities using the above formula. 3) Solving trigonometric equations. (Use of general solutiions, for sinx, cosx and tanx, to solve a trigonometric equation in a given inte
