sum or difference identity for sine The sum and difference identities are used to solve various mathematical problems and prove the trigonometric formulas and identities In this article we will discuss the sum and difference formulas for sine cosine and tangent
We can use the sum and difference formulas to identify the sum or difference of angles when the ratio of sine cosine or tangent is provided for each of the individual angles The Sine Difference and Sum Identities We can now use the Cosine Difference Identity and the Cofunction Identities to derive a Sine Difference Identity sin A B cos dfrac pi 2 A B
