trigonometry summation formula Learn how to use sum and difference formulas for cosine sine and tangent to simplify trigonometric expressions and equations See proofs examples and applications of these
These are also known as the angle addition and subtraction theorems or formulae The angle difference identities for and can be derived from the angle sum versions by substituting for and using the facts that and They can also be derived by using a slightly modified version of the figure for the angle sum identities b Summary Continuing with trig identities this page looks at the sum and difference formulas namely sin A B cos A B and tan A B Remember one and all the rest flow from it There s also a beautiful way to
