"WebImportant Notes on Sin Double Angle Formula. Sin Double Angle Formula can be expressed in terms of different trigonometric functions. The formula for sin2θ can be expressed as: sin2θ = 2 sinθ cosθ; sin2θ = 2tanθ / (1 + tan 2 θ) We can prove the sin double angle formulas using the sin (A + B) formula and other trigonometric identities.
