Explain how the chain rule is applied to geometric problems with angles that are change over time ("related rates"). I'm having difficulties developing a relationship. App. The procedure to solve a related rate problem is: related rates of change. 10, Ex. 2 4 r h 500 Ө y In this part of height and distances we will be discussing about angle of elevation in detail. How fast is the plane traveling at that time? What rate of change is necessary for the elevation angle of the camera if the camera is placed on the ground at a distance of \(4000ft\) from the launch pad and the velocity of the rocket is 500 ft/sec when the rocket is \ Question: Draw the situation and solve the related-rate problem You are stationary on the ground while you watch a bird fly horizontally at a rate of 14 m/s away from you. How fast is the shadow cast by a 200-ft-tall building increasing when the angle of elevation of the sun is a /6? Include an appropriate picture that shows your variables.
