Instantaneous Rate of Change Formula in Calculus

In calculus, the instantaneous rate of change of a function is the slope of the tangent line of the graph of the function at a specific point. The instantaneous rate of change formula is directly related to the derivative of the function.

For any function

For any function 𝑓(𝑥)f(x), the instantaneous rate of change at 𝑥=𝑎x=a is given by:

f'(a)him/h⇾0  f(a+h)-f(a)/h

This formula helps you find the slope of the tangent line at the point 𝑎, which represents the instantaneous rate of change of the function at that point.

Example:

Suppose you have a function 𝑓(𝑥)=𝑥2f(x)=x 2 and you want to calculate the instantaneous rate of change at 𝑥=2x=2.

The derivative of this function will be:

f'(x)=2x

Now let's evaluate the derivative of 𝑥=2x=2:

f '(2)=2(2)=4

So, the instantaneous rate of change of 𝑓(𝑥)=𝑥2f(x)=x 2 at 𝑥=2x=2 is 4.

Frequently Asked Questions (Q&A)

1. What is instantaneous rate of change?

Instantaneous rate of change is the slope of a function at a specific point. Meaning, it tells how fast the function is changing at that point. This slope is of the tangent line that touches the curve at that point.

2. What is the instantaneous rate of change formula?

The formula of instantaneous rate of change is based on the concept of derivative in calculus. Its formula is:

f'(a)him/h⇾0  f(a+h)-f(a)/h

​

This limit is the difference between two close points of the function, and when it approaches zero, you get the exact slope at that point.

3. What is the instantaneous rate of change equation?

The instantaneous rate of change equation is in the form of a derivative. If you have a function 𝑓(𝑥)f(x), then its instantaneous rate of change is 𝑓′(𝑥)f ′(x), which is the derivative of the function. This equation tells how the function will behave at any point.

4. How is the instantaneous rate of change formula used in calculus?

In calculus, the instantaneous rate of change formula is used to calculate the speed or rate of a function at a particular point. This formula is related to the concept of limit and derivative, which finds the slope of the function via a tangent line.

5. How to calculate instantaneous rate of change in calculus?

To calculate instantaneous rate of change, the first step is to find the derivative of the function. Then, you evaluate the derivative at a given point of the function. This process gives the slope of the tangent line which tells how much the function is changing at that point.

This Instantaneous Rate of Change Calculator is the best tool to simplify your calculus problems. It helps to easily calculate derivative and instantaneous rate of change, and also makes it easy to understand the concept through step-by-step calculations and graphs.

Through this calculator, besides understanding the complex concepts of calculus, you can also use them in practical real-world applications.
