WebDouble Angle Formulas. Double-angle formulas can be expanded to multiple-angle functions (triple, quadruple, quintuple, and so on) by using the angle sum formulas, and then reapplying the double-angle formulas. s i n ( A + B) = s i n A c o s B + c o s A s i n B. s i n ( A − B) = s i n A c o s B − c o s A s i n B. WebUse a half-angle identity to find the exact value of each function. =±1−cos30°2 =±1−322 =±2−32 Since 15⁰ is a first quadrant angle and sine is positive in the first quadrant, choose the positive value. sin15°=2−32
