My derivative seems wrong so I need a walkthrough of this problem:
An airplane flies at an altitude of 4.5 miles towards a point directly overhead. The plane is flying at a rate of 190 mph. Find the rate at which the angle of elevation, theta, is changing per minute when theta = .45 radians. Use D for ground distance to a point under the plane and L as distance directly from the plane.
What is the equation for theta?
What is the implicit derivative?
Calculate the derivative of theta with respect to time using the values above.
Thanks!
