A half-angle identity is a particular type of trigonometric identity that relates a trigonometric function to another trigonometric function where one function has as an argument an angle that is half of the value of the angle of the other function's argument. Some examples of half-angl...
Half-angle formula for sine function: {eq}\sin 2\theta=2\sin \theta\cos \theta {/eq} Answer and Explanation:1 We are given a trigonometric expression. We want to prove that it is an identity. Using the identities on the context section we have that: ...
Sine and Cosine are two of 6 trigonometric functions that we have. To evaluate the given expression, we have here used trigonometric trivial identity values and half angle identity rules.Answer and Explanation: We're given: $$2\cos \left(11.25^{\circ \:}\right)\sin \left(11.25^{\circ...
