Trigonometric Ratios of Compound Angles . An angle made up of the algebraic sum of two or more angles is called a compound angle. Some of the formulae and results regarding compound angles are: sin(A + B) = sinA cosB + coA sinB. sin(A – B) = sinA cosB – cosA sinB. cos(A + B) = cosA cosB – sinA sinB. cos(A – B) = cosA cosB + sinA sinB
