Question
Below are the four options presented for solving an equation involving values of π: a. \( x = \frac{\pi}{8}, \frac{7\pi}{8}, \frac{9\pi}{8}, \frac{15\pi}{8} \) b. \( x = \frac{\pi}{8}, \frac{7\pi}{8} \) c. \( x = \frac{\pi}{4}, \frac{5\pi}{4}, \frac{7\pi}{4}, \frac{11\pi}{4} \) d. \( x = \frac{\pi}{4}, \frac{7\pi}{4} \) Each option provides different sets of values for \( x \) in terms of π. - Option (a) presents four values, which are \( \frac{\pi}{8}, \frac{7\pi}{8}, \frac{9\pi}{8}, \frac{15\pi}{8} \). - Option (b) presents two values, which are \( \frac{\pi}{8}, \frac{7\pi}{8} \). - Option (c) provides four values, which are \( \frac{\pi}{4}, \frac{5\pi}{4}, \frac{7\pi}{4}, \frac{11\pi}{4} \). - Option (d) lists two values, which are \( \frac{\pi}{4}, \frac{7\pi}{4} \). These options may correspond to possible solutions for trigonometric or other mathematical equations in a particular context. Each option should be evaluated based on the given problem statement or equation for correctness.
