    When we project a ball upwards, its position changes with respect to time, and its velocity changes as its position changes. The height of a person changes with time. The prices of stocks and options change with time. The equilibrium price of good changes with respect to demand and supply.

    The power radiated by a black body changes as its temperature changes. The surface area of a sphere changes as its radius changes. This list never ends. It is amazing to measure and study these changes. Imagine that you drive to a grocery store 10 miles away from your house, and it takes you 30 minutes to get there. The speed of your car is a great example of a rate of change.

    Average and Instantaneous Rate of Change A rate of change tells you how quickly something is changing, such as the location of your car as you drive.

    You can also measure how quickly your hair grows, how much money your business makes each month, or how much water flows over a dam. All of these, and many more, can be represented by calculating the average rate of change of a quantity over a certain amount of time. One easy way to calculate a rate of change is to make a graph of the quantity that is changing versus time. Then you can calculate the rate of change by finding the slope of the graph, like this one. The slope is found by dividing how much the y values change by how much the x values change.

    These changes depend on many factors; for example, the power radiated by a black body depends on its surface area as well as temperature. We shall be looking at cases where only one factor is varying and all others are fixed. Instantaneous Rate Of Change Calculator So, we saw that you could calculate the average rate of change by calculating the slope of a line, but does that work for instantaneous rates of change as well?

    In fact, it does, although you have to think about slope a little differently than you may have before. If you have a graph of your position vs. The slope of this tangent line will give you the instantaneous rate of change at exactly that point. As you can see from the calculation on this graph, v equals 20 meters divided by 5 seconds minus 1. How does that compare to the average rate of change?

    To determine your average speed over the whole trip, calculate the slope of a line drawn from the first point on the graph to the last point. Find the average rate of change of the xx-coordinate of the car with respect to time. We calculated that your average speed for the entire trip was 20 miles per hour, but does that mean that you were traveling at exactly 20 miles per hour for the entire trip?

    When you measure a rate of change at a specific instant in time, this is called an instantaneous rate of change. An average rate of change tells you the average rate at which something was changing over a longer time period.

    While you were on your way to the grocery store, your speed was constantly changing. Sometimes you were moving faster than 20 miles per hour and sometimes slower. At each instant in time, your instantaneous rate of change would correspond to your speed at that exact moment.

    Instantaneous Rate Of Change Calculus First, both of these problems will lead us into the study of limits, which is the topic of this chapter after all. Looking at these problems here will allow us to start to understand just what a limit is and what it can tell us about a function.

    So, looking at it now will get us to start thinking about it from the very beginning. Before getting into this problem it would probably be best to define a tangent line. Take a look at the graph below. In general, we will think of a line and a graph as being parallel at a point if they are both moving in the same direction at that point. So, in the first point above the graph and the line are moving in the same direction and so we will say they are parallel at that point.

    3.4 Derivatives as Rates of Change

    What is the formula for instantaneous velocity? Instantaneous Rate of Change — A rate of change tells you how quickly something is changing, such as the location of your car as you drive. You can also measure how quickly your hair grows, how much money your business makes each month, or how much water flows over a dam.

    All of these and many more can be represented by calculating the average rate of change of a quantity over a certain amount of time.

    One easy way to calculate the rate of change is to make a graph of the quantity that is changing versus time. Then you can calculate the rate of change by finding the slope of the graph, like this one. The slope is found by dividing how much they values change by how much the x values change.

    Instantaneous Rate of Change We see changes around us everywhere. When we project a ball upwards, its position changes with respect to time, and its velocity changes as its position changes. The height of a person changes with time. The prices of stocks and options change with time. The equilibrium price of good changes with respect to demand and supply.

    The power radiated by a black body changes as its temperature changes. The surface area of a sphere changes as its radius changes.

    This list never ends. It is amazing to measure and study these changes. Instantaneous Rate of Change These changes depend on many factors, for example, the power radiated by a black body depends on its surface area as well as temperature. We shall be looking at cases where only one factor is varying and all others are fixed. In this graph, you can see how the blue function can have its instantaneous rate of change represented by a red line tangent to the curve.

    To find the slope of this line, you must first find the derivative of the function. Practicing a similar rate of change problems will help you get a feel for the practical uses of derivatives. Instantaneous Rate of Change Formula The rate of change at one known instant is the Instantaneous rate of change, and it is equivalent to the value of the derivative at that specific point.

    So it can be said that, in a function, the slope, m of the tangent is equivalent to the instantaneous rate of change at a specific point. One more method to comprehend this concept clearly is with the difference quotient and limits. The average rate of change of y with respect to x is the difference quotient. In guileless words, the time interval gets lesser and lesser.

    Is the derivative the instantaneous rate of change? The Derivative as an Instantaneous Rate of Change. Is instantaneous velocity the same as the instantaneous rate of change? Velocity is one kind of rate of change.

    It is the rate of change of position with respect to time. The rate of change is more general and includes velocity as one example. Is the instantaneous rate of change a limit? Your final answer is right, so well done. The instantaneous rate of change, i. You need the limit notation on the left of all of your expressions, i.

    What is the instantaneous change used for? When you measure a rate of change at a specific instant in time, this is called an instantaneous rate of change. An average rate of change tells you the average rate at which something was changing over a longer time period.

    It is simply the process of calculating the rate at which the output y-values changes compared to its input x-values. How do you find the average rate of change? We use the slope formula! Average Rate Of Change Formula To find the average rate of change, we divide the change in y output by the change in x input.

    And visually, all we are doing is calculating the slope of the secant line passing between two points. All you have to do is calculate the slope to find the average rate of change!

    While both are used to find the slope, the average rate of change calculates the slope of the secant line using the slope formula from algebra.
