1.8.2 Small angle approximations (A-level only)

Question 1

In a precision engineering simulation, the vertical displacement $h$ of a micro-lever is modeled by the equation $15\cos(4\theta) - 6$ , where $θ\theta$ is a small angle measured in radians. Using small angle approximations, find a simplified expression for $h$ in terms of $θ\theta$ .
