Problem 1 (2.74 from the textbook) Suppose that the height of an object in meters at time in seconds is given by A(t) = 4 + 0.130 . Further suppose that the object is being tracked by a camera 10 meters away. Find an expression for the rate of rotation of the camera at time t. In other words, find an expression for the derivative of 0. Hint: you will need the formula for the derivative of the inverse tangent function, which appears on page 85 of the textbook. Camera Problem 2 (2.77(e) from the textbook) Find & if y = plan(z)
