Trigonometry is an important chapter of Mathematics for the level of class 10 and 12 and often children are confuses regarding the formulas of this chapter. Here is a chapter wise list of all the trigonometric formulas which are widely required while doing the sums of Trigonometry. 
Formulas for Compound Angles of trigonometry
sin (A + B) = sin A.cos B + cos A.sin B. sin (A - B) = sin A.cos B - cos A.sin B. cos (A + B) = cos A.cos B - sin A.sin B. cos (A - B) = cos A.cos B + sin A.sin B. sin (A + B).sin (A - B) = sin^2 A- sin^2 B. sin (A + B).sin (A - B) = cos^2 B - cos^2 A. cos (A + B).cos (A - B) = cos^2 A - sin^2 B. cos (A + B).cos (A - B) = cos^2 B - sin^2 A. tan (A + B) = {tan A + tan B}/{1 - tan A.tan B}. tan (A - B) = {tan A - tan B}/{1 + tan A.tan B}. cot (A + B) = {cot A.cot B - 1}/{cot B + cot A}. cot (A - B) = {cot A.cot B + 1}/{cot B - cot A}. tan (A + B + C) = {tan A + tan B + tan C - tan A.tan B.tan C}/{1 - tan A.tan B - tan B.tan C -tan C.tan A}.
