WebbThe quotient identities are the trigonometric identities written in terms of the fundamental trigonometric functions, sine, and cosine. Let’s consider the sine, cosine, and tangent functions. If we define these functions in a right triangle, we have the following: \sin (\theta)=\frac {O} {H} sin(θ) = H O. \cos (\theta)=\frac {A} {H} cos(θ ...

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.
