![**Title: Calculating Rates of Change in Circular Motion**
Batman is at it again, driving his vehicle frantically around Wayne Manor (luckily avoiding Alfred’s freshly planted patch of dwarf cypress and gardenia). This time, the Batmobile moves counterclockwise along a circular path given by the equation:
\[ x^2 + y^2 = 4. \]
Let \(\theta\) denote the angle formed between the Batmobile and the positive x-axis at time \(t\).
**1. Problem 1**
At the moment the Batmobile passes through the point \((\sqrt{2}, \sqrt{2})\), its vertical velocity (in miles per hour) is given by:
\[ \frac{dy}{dt} = 30 \text{ mi/hr}. \]
Find the rate (in radians per hour) at which the angle \(\theta\) is moving at this time.
**2. Problem 2**
At the moment the Batmobile passes through the point \((-1, \sqrt{3})\), the angle \(\theta\) is changing at a rate given by:
\[ \frac{d\theta}{dt} = 3 \text{ rad/hr}. \]
