Introduction to Derivative at a Point Calculator

A derivative calculator is an online tool that allows you to calculate a derivative at a given point of the function without solving the long-term calculations. It uses the function value as an input and an interval at which you want to calculate the rate of change of that function.

In calculus, the Derivative at a point is an important concept that finds the rate of change of any function. It approximates the given function at the end of change. We introduce a tool online that helps you to calculate derivatives at a given point on the tangent line.

How to use Derivative at a Point Calculator with Steps?

It is not difficult to find derivatives at a point using this tool because it provides you with an easy and fast solution to your mathematical problems. There are some simple and easy steps to use this tool. These are:

  • Write the value of the function in the “Enter Function.”
  • Select the order of derivatives from the “computes with.”
  • Now select the point from the “When x=.”
  • Click on the “Calculate button after reviewing the function that appears when you insert the input value.

You will get the solution within a minute of clicking the calculate button.

Online Derivative Calculator with Steps Formula

The derivative at a point refers to approximating a function on a point. In this differentiation, we first find the derivative of the function and then substitute the point in it.

Formula

Let f be a function and there is a point x=a in the domain of f(x). Then the derivative of f(x) with respect to the point x=a is,

$$ f'(a) \;=\; \frac{f(a+h)-f(a)}{h} $$

Where,

f'a= Derivative at a.

Derivative at a point calculator uses this formula to approximate a given function with respect to the point.

How to Find Derivative at a Point Online Calculator?

It is not difficult to find this tool online. You can search it from your browser. It is available on the calculator website. There are also a variety of different mathematical tools on this website.

Why use Derivative at a Point Formula Calculator?

The Derivative at a point and the ordinary Derivative are two confusing but essential concepts for students. This concept helps to find the slope of a tangent line to a function’s graph at a point. Therefore, it has many applications in mathematics and physics. For example, finding the slope at a certain point is done by finding the Derivative at that point.

You can get confused with the formula when calculating the Derivative at a point by manual calculations. It is because the ordinary Derivative and the Derivative at a point consist of almost the same formulas. There is only a little difference, which makes it confusing for students. Therefore, you need to use this tool to avoid confusion. if you want to find derivative of extreme point quickly you can also use online extreme point calculator.

Benefits of using Second Derivative at a Point Calculator

FAQ’s

What is the derivative formula?

Let f(x) be a function, the derivative of f(x) calculates the rate of change with respect to an independent variable. Then the derivative formula is;

$$ f'(x) \;=\; \frac{f(x+δx)-f(x)}{δy} $$

How do you find the derivative at a point?

You can calculate the derivative at a point for a function f(x) at x=a by using the following formula,

$$ f'a \;=\; \frac{f(a+h)-f(a)}{h} $$

Let fx=2x3+1, to calculate its derivative at x=2 , We will use the following steps.

$$ f(x) \;=\; 2x^3 \;+\; 1 $$

Applying derivatives of both sides with respect to ‘x’.

$$ f'(x) \;=\; \frac{d}{dx} (2x^3 \;+\; 1) $$ $$ f'(x) \;=\; 2×3x^{3-1} \frac{d}{dx} (x) \;+\; \frac{d}{dx} (1) $$ $$ f'(x) \;=\; 6x^2 $$

So derivative at x=2,

$$ f'(2) \;=\; 6(2)^2 \;=\; 6(4) $$ $$ f'(2) \;=\; 24 $$
