Unformatted text preview: 3. Identify the rate that you are looking for: 4. Determine the Primary Equation (if necessary, use a Secondary Equation to eliminate extra variables): 5. Differentiate both sides of your Primary Equation with respect to time and solve for the rate youre looking for: Example: A ladder 25 feet long is leaning against the wall of a house. The base of the ladder is pulled away from the wall at a rate of 2 feet per second. Find the rate at which the angle between the ladder and the wall of the house is changing when the base of the ladder is 7 feet from the wall. 1. Draw a Picture of the problem: 2.
