On a unit circle where the hypotenuse is 1, the {eq}\sin\alpha {/eq} is reduced to the length of the opposite side, (hypotenuse is 1) the {eq}\cos\alpha {/eq} is the length of the adjacent side, and then the first identity reveals itself:$$\tan\alpha=\frac{\sin\alpha}{\cos...
Use the double-angle identity to find the exact value for cos(2x) given sin(x) = sqrt(2)/4. Verify the trigonometric identity. \sec y \cos y = 1 Verify whether the following equation is an identity. (5 cos x - 2 sin x)^2 + (2 cos ...
functions, because it's often unclear which identity or formula to use. For example, in the equation sin x cos x = 1/4, use the double angle formula cos 2x = 2 sin x cos x to substitute 1/2 cos 2x in the left side of the equation, yielding the equation 1/2 cos 2x = 1/4....
