What Are Double-Angle Formulas?

Double-angle formulas are trigonometric identities that allow you to express trigonometric functions of double angles (2θ) in terms of single angles (θ). These formulas are particularly useful for simplifying expressions and solving equations. You have to memories these formulas. You can easily remember them by using addition and difference formulas.  

sin2A = 2sinAcosA

cos2A=cos2A-sin2A
