Quizplus · Accepted Answer

The equation $- 1 = \tan ^ { 2 } x$ can be rewritten using the trigonometric identity $\tan^2x + 1 = \sec^2x$, which simplifies to $\sec^2x = 0$, indicating that the correct answer involves the secant function.

Perform the Indicated Operations and Simplify the Result So There −1=tan⁡2x- 1 = \tan ^ { 2 } x−1=tan2x
