Related rates are calculus problems that involve finding a rate at which a quantity changes by relating to other known values whose rates of change are known. For instance, if we pump air into a donut floater, both the radius and the balloon volume increase, and their growth rates are rela...
Related rates problem In a related rates problem, we are given the rate of change of one or more quantities, and are required to find the rate of change of one or more related quantities. For instance (as in the first example in Section 5.5 of Applied Calculus or Section 12.5 of Finite...
You see, a rate of change is the speed at which a quantity is changing over time. We have two quantities which are related to each other, and we want to know how their rates of change are related to each other.(By the way, sometimes we’ll abbreviate and say “rate” instead of ...
3.9 Related Rates In this section, we will learn: How to compute the rate of change of one quantity in terms of that of another quantity. DIFFERENTIATION. Examples of Questions thus far…. Related Rates Objective: To find the rate of change of one quantity knowing the rate of change of ...
