When we add or subtract angles, the result is called a compound angle. i.e.,the algebraic sum of two or more angles are called compound angles. For example, If A, B, C are three angles then A ± B, A + B + C, A – B + C etc., are compound angles. 2. Sum and difference formulae of sine, cosine and tangent. 3. Trigonometric ...
