For students who need to answer this question in their tests or academic assignments, there are certain examples and relevant terms that should be considered. For example, when you drive to a local shop, it’s obvious that you can’t go with the same speed all the time. This speed is not the only example when it comes to a rate of change that has 2 main types, average and instantaneous. If you can’t complete instantaneous rate of change homework for any reason, including your lack of time or knowledge, the good news is that freelancers offer helpful services online.

What is it all about? To get a clear idea of the instantaneous rate of change, you need to learn more about a range of change in general. Imagine that you drive to a local shop situated ten miles away from home, and it usually takes around thirty minutes to get there. This means that your average speed is twenty miles per hour, and the speed of a car is another excellent example when studying a rate of change. It can tell you how fast something changes, including the location of this car as you keep driving it. Besides, it allows you to measure how fast your hair can grow, how much water flows over a particular dam, how much profit a business can earn on a monthly basis, and so on. These examples can be represented if you succeed to calculate the average rate of change, which is different from the instantaneous rate of change.
Keep in mind that one of the easiest ways to calculate it is by making a certain graph of the quantity that is changed over time. It’s also possible to calculate a range of change if you find the slope of a given graph, and this goal is easy to achieve by dividing how much y and x values change. Feel free to find the necessary speed by determining the slope of a line on a specific position vs. a time graph.
To get a better understanding of the instantaneous rate of change, you should compare it with the average type. For example, remember your trip to a local shop again because you already know that its average speed is twenty miles per hour. The next thing that should be determined is whether it changes at any point of time. Think about your stops at red lights and other similar situations that force you either to increase or decreasing this speed. When measuring a range of change at any particular moment, this means that you’re dealing with the instantaneous rate of change. The basic purpose of an average rate is to tell you an average rate at which something changes over a certain period of time. As an example, your speed keeps changing on your way to a local shop because you may move both faster and slower. The speed at which you’re moving at the exact moment corresponds to the instantaneous rate of change.
If you’re asked by professors to calculate an instantaneous rate from a graph, you should learn a few basic steps involved in this process. When it comes to an average rate, it’s easy to calculate it from finding a slope of a given line, but this method doesn’t work for the other type. The main reason is that you need to think about a slope in a different way. Imagine a graph with your position and time, which is not a straight line because it can help you calculate the instantaneous rate of change. However, it’s necessary to draw a tangent line that intersects a given graph at only one point. Remember that the slope of this line provides you with the necessary rate at that point. Another important detail is that it also tells you more about the instantaneous speed.
How does it compare to the average type? If you need to define the average speed over the entire trip, start with calculating a slope of a line, but make sure that it’s drawn from the 1st point to the last point of a given graph. If your basic target is finding the average speed, it’s required to take this step to find a slope. Besides, you can calculate the instantaneous rate of change through calculus. Once you get the instantaneous speed by using a graph, you need to draw a tangent line that touches it at only one point. The next step that should be taken is calculating a slope line to end up with the answer you need. When it comes to calculus, a slope of any tangent line is often called a derivative. Once you get the equation that describes the exact position of your car, it becomes possible to find a derivative, thus resulting in a new equation for its speed at any moment of time.
When studying the instantaneous rate of change, don’t forget that it’s also called a derivative. Basically, it’s a function used to tell you how fast a relationship between given variable (y and x) is changing at a given point. Imagine that you take up archery lessons, and when you shoot an arrow, it leaves a bow fast and keeps slowing down until it hits the chosen target. Your skills are not so good at first, but they get better over time, and arrows leave a bow with a greater speed and pierce targets because they still travel fast. Take a look at this difference in shooting skills, as it can tell you more about the meaning of the instantaneous rate of change. It’s all about the speed at which your arrows travel at the moment when they make contact.
When studying mathematics, you may often think of this rate as a certain slope. The latter one can be considered as a change in y values divided by the change in x values. The main problem with the instantaneous rate of change is that it refers to only one moment in time, which means that this change in y values happens when the change in x values is only an instant or technically 0.
If you put 0 into the denominator of a standard slope formula, you will end up with a problem because dividing by 0 causes the universe to implode. What can you do with that? One of the easiest methods used by math students is using certain limits from calculus. You need to ask what happens to a given slope as 0 gets closer and closer to 0 instead of putting it in a denominator directly. Remember your archery example, as this means that you should look at how much distance your arrows can travel over a limited period of time to make it smaller and smaller until it’s nearly 0. For some students, this formula may not seem a sound solution for the instantaneous rate of change, but it’s advisable to do some algebraic manipulations to get the right answer from it.
