Step 1 :Substitute \(\cos(2\theta)\) with \(1 - 2\sin^2(\theta)\) in the given equation to get \(8(1 - 2\sin^2(\theta)) = 8\sin^2(\theta) + 5\)
Step 2 :Simplify the equation to get \(8 - 16\sin^2(\theta) = 8\sin^2(\theta) + 5\)
Step 3 :Rearrange the terms to get \(24\sin^2(\theta) = 3\)
Step 4 :Divide both sides by 24 to get \(\sin^2(\theta) = \frac{1}{8}\)
Step 5 :Take the square root of both sides to get \(\sin(\theta) = \pm \frac{\sqrt{2}}{4}\)
Step 6 :Find the values of \(\theta\) that satisfy the equation in the interval \(0 \leq \theta < 2\pi\). For \(\sin(\theta) = \frac{\sqrt{2}}{4}\), we get \(\theta = \frac{\pi}{6}, \frac{5\pi}{6}\)
Step 7 :For \(\sin(\theta) = -\frac{\sqrt{2}}{4}\), we get \(\theta = \frac{7\pi}{6}, \frac{11\pi}{6}\)
Step 8 :\(\boxed{\text{So, the solutions to the equation are } \theta = \frac{\pi}{6}, \frac{5\pi}{6}, \frac{7\pi}{6}, \frac{11\pi}{6}}\)
