Where does cos(x) equal 1/4? Prove the following identity: sin(3x) = 3 cos^2(x) sin(x) - sin^3(x). What is the simplified form of (1 - cos^2(x)) / (cos(x)tan(x))? Simplify the expression (cos^2(x) - sin^2(x))/(1 - tan^2(x)). Verify the identity: sin 4x...
What does {eq}\arctan 0 {/eq} equal?Trigonometric Identities:The tangent identity in trigonometry is derived from the sine and cosine identities i.e., {eq}\tan x=\dfrac{\sin x}{\cos x} {/eq}. The inverse tangent function is represented as {eq}\arctan {/eq}....
