Identities: In trigonometry, an equation consisting of any of the six trigonometric ratios (sine, cosine, tangent, secant, cosecant, and tangent) becomes an identity, when such equation holds true for any random value of the unknown. For example, sin2x+cos2x=1 is an identity since si...
Answer and Explanation:1 To solve this equation, we need to express the trigonometric functions with respect to the same argument: {eq}\sin 2x = \cos x,\quad 0\leq x\leq 2\pi... Learn more about this topic: Solve Trigonometric Equations with Identities & Inverses ...
