To solve the equation \( \log_{\cos x} \left( \frac{\sqrt{3}}{2} \sin x \right) = 2 - \log_{\sec x} (\tan x) \), we will follow these steps: ### Step 1: Rewrite the logarithm on the right-hand side We know that \( \log_{\sec x} (\tan x) \) can be rewritten using the change of base formula: \[ \log_{\sec x} (\tan x) = \frac{\log(\tan x)}{\log(\sec x)} \] Since \( \sec x = \frac{1}{\cos x} \), we can express \( \log(\sec x) \) as \( -\log(\cos x) \). Thus, ...
