WebbDouble angle formulas: The double angle trigonometric identities can be obtained by using the sum and difference formulas. For example, from the above formulas: sin (A+B) = sin A cos B + cos A sin B Substitute A = B = θ on both sides here, we get: sin (θ + θ) = sinθ cosθ + cosθ sinθ sin 2θ = 2 sinθ cosθ WebbRecall from the last section, the sine of the sum of two angles: sin (α + β) = sin α cos β + cos α sin β. We will use this to obtain the sine of a double angle. If we take the left hand side (LHS): sin (α + β) and replace β with α, we get: sin (α + β) = sin (α + α) = sin 2 α. Consider the RHS: sin α cos β + cos α sin β.
