    The equivalent of tan (-x) cos 2x among the choices can be determined by substituting a value of x. For example, x is equal to 1. The value of tan (-1) cos (2*1) is 0.6481. we substitute 1 to each of the choices. The trigonometric terms with the same answer is D. tan (-1) cos (2*1) is also 0.6481. Answer is D.
