1. The problem is to simplify the expression $3 - 4\cos(\theta)$, where $\theta$ is an angle. 2. The expression involves a constant term and a cosine function multiplied by a constant. 3. There is no further simplification possible without additional context or values for $\theta$. 4. This expression can be used as is in trigonometric calculations or graphing. Final answer: $3 - 4\cos(\theta)$
