Yr 12 - Fri Feb 1st - Finding the rate of change of a functionat a particular point

LEARNING OBJECTIVE: DIscover how to use differentiation to solve problems where one variable changes with respect to another variable.
SUCCESS CRITERIA: You will be able to use differntiation to solve real life problems

FACTS:

• The rate of change of velocity with respect to time is known as acceleration
• The rate of change of displacement with respect to time is known as velocity

LESSON:

example: Given that volume of an expanding sphere is related to its radius by the equation V= 4/3 πr^{3, find the rate of change of the volume with respect to the radius at the instant where the radius = 5cm.}
