Verify the identity. sin (α + ẞ) cos α cos ẞ = tan α + tan ẞ Rewrite the numerator on the left side of the identity using one of the sum and difference formulas. COS α cos B Rewrite the fraction from the previous step such that it is a sum or difference of two expressions. Do not simplify the rea Divide out any common factors in the expression from the previous step. The expression from the previous step then simplifies to tan a+ tan ẞ using what? OA. Reciprocal Identity OB. Pythagorean Identity OC. Quotient Identity OD. Even-Odd Identity OE. No identity is required. Evaluate the previous expression wherever possible and simplify.
