Webθ − 2ysin 1 2 θ cos 1 2 θ = 0. (16) If θ 6= 0 (mod 2 π), then we can divide both sides of eq. (16) by sin 1 2 θ to obtain1 xsin 1 2 θ − ycos 1 2 θ = 0. (17) We recognize eq. (17) as an equation for a straight line that passes through the origin with a slope equal to tan 1 2 θ. Thus, we have demonstrated that the most general Web7.5 Solving Trigonometric Equations - Precalculus 2e OpenStax Uh-oh, there's been a glitch We're not quite sure what went wrong.

Now substitute 2φ = θ into those last two equations and solve for sin θ/2 and cos θ/2. Then the tangent identity just follow from those two and the quotient identity for tangent. 1 comment WebDec 20, 2024 · A trigonometric identity is an equation involving trigonometric functions that is true for all angles θ for which the functions are defined. We can use the identities to help us solve or simplify equations. The main trigonometric identities are listed next.
