Chapter 2: Problem 10

In your own words, state the guidelines for solving related-rate problems.

Short Answer

Expert verified
The guidelines for solving a related-rate problem include understanding the problem, drawing a representation if possible, identifying known rates and the rate to find, forming an equation that relates the quantities involved, differentiating this equation with respect to time, and solving for the unknown rate.

Step by step solution

01

Understand the Problem

The first step to solving any related-rates problem is to read and understand the problem carefully. Make sure to identify what rates are given and what rate we need to find.
02

Draw a diagram if possible

If the problem involves a physical scenario, drawing a diagram can often help visualize the situation and identify the variables involved.
03

Write down what you know

Based on the problem, write down what rates are known and what rate is to be found.
04

Setup a relationship

Create an equation that relates the various quantities involved in the problem. This is generally based on some principle of physics, geometry, etc.
05

Differentiate the equation

Differentiate both sides of the equation with respect to time. This step brings in the rate of change of the various quantities involved.
06

Solve for the unknown

Substitute all known quantities (and their rates) into the equation from Step 5, then solve for the unknown rate.

Volume The radius \(r\) of a sphere is increasing at a rate of 3 inches per minute. (a) Find the rates of change of the volume when \(r=9\) inches and \(r=36\) inches. (b) Explain why the rate of change of the volume of the sphere is not constant even though \(d r / d t\) is constant.

Acceleration The velocity of an object in meters per second is $$ v(t)=36-t^{2} $$ for \(0 \leq t \leq 6 .\) Find the velocity and acceleration of the object when \(t=3 .\) What can be said about the speed of the object when the velocity and acceleration have opposite signs?

Using Absolute Value In Exercises \(119-122,\) use the result of Exercise 118 to find the derivative of the function. $$ h(x)=|x| \cos x $$

Finding a Second Derivative In Exercises \(91-98\) , find the second derivative of the function. $$ f(x)=x^{4}+2 x^{3}-3 x^{2}-x $$

True or False? In Exercises \(129-134\) , determine whether the statement is true or false. If is false, explain why or give an example that shows it is false. The second derivative represents the rate of change of the first derivative.
