Introduction to Normal Line Calculator

The normal line equation calculator is an online mathematical tool that is used to calculate a normal line of a given equation. It allows you an efficient method to evaluate the line that is perpendicular to the tangent line on the curve at a specific point. It can handle a wide range of horizontal as well as vertical normal lines.

The Normal Line Calculator deals with single-variable functions and focuses on tangent lines and perpendicularity, whereas our jacobi calculator deals with multivariable functions and pertains to transformations and coordinate systems.

What is the Normal Line?

A normal line is a line that draws at a right angle (90 degrees) at the tangent line of a graph at a particular point where they intersect each other. If you sketch a curve and the tangent then the line that meets the tangent line at 90 degrees at that point is known as a normal line.

The normal line to a curve at a given point is a straight line that is perpendicular to the tangent line at that point.

In simpler terms, if you imagine a curve as a path traced by a moving point, the tangent line represents the direction in which the point is moving at a specific instant. The normal line, on the other hand, is perpendicular to this tangent line and extends outward from the curve.

Additionally, if you would like to calculate Hessian Matrix of any multivariable functions, you can use our hesse matrix calculator. Our calculator also evaluates the determinate of the second-order partial derivative functions of n by n matrix to get information about the curvature of a given function.

Formula Behind Our Normal Equation Calculator

For finding the normal line, Our tangent and normal line calculator uses the following formula so that the exact answer can be found,

$$ y-y_1 \;=\; - \frac{1}{f'(x_1)}(x-x_1) $$

Operating Procedure of the Normal Line Equation Calculator

Equation of normal calculator can give solutions of any type of equation like explicit, implicit, parametric, and polar to find normal line problems because its server has advanced algorithms to solve complex tangent line questions without any error.

You need to enter the function and the point value first. Then the normal line to surface calculator differentiates the function f(x) and adds the x point value in f`(x) to get the value of the x-coordinate. After that add the x point value in f(x) to get the value of the y-coordinate.

In the last add x and y coordinate values in the equation of the slope of the tangent line to get the solution of the normal line equation. You can also get solutions in the form of detailed steps which will help you to understand normal line concepts easily while using our normal equation calculator.

Let's discuss an example of the normal line problem to know the working of our normal line calculator.

Additionally, for further exploration of calculus concepts, including linear approximation, you can utilize our approximate value calculator. It offers a comprehensive tool for approximating functions using tangent lines, aiding in calculus analysis.

Solved Example of the Normal Line

An example of a normal line problem with a solution is given below to help you understand the manual calculations,

Example:

Find the normal line at the point while considering the function f(x) = x3. Where x = 1.

Solution:

The derivative of f(x):

$$ f’(x) \;=\; 3x^2 $$

At x = 1, the slope of the tangent line is 3, so for the normal line the slop will be -⅓. The y-coordinate is:

$$ f(1) \;=\; (1)^3 \;=\; 1 $$

So the point is (1, 1).

The equation of the normal line is:

$$ y - 1 \;=\; -⅓ (x - 1) $$

Frequently Asked Question

What is a Normal Line

A normal line to a curve on a given point is the line that is perpendicular to the tangent line on that point. The normal line is perpendicular to the tangent line on any given point on the curve or surface.

There is only one unique normal line in a two-dimensional plane for a given point on a curve. In three-dimensional space, the normal line points in two opposite directions as it is perpendicular to the entire plane.

On the curve or the surface, the normal line depends on the point of contact. The result is when the point of contact changes there would be a different normal line. Also, when dealing with the normal vectors, the magnitude of the normal vector is not standardized and can be any positive value.

How to Find Normal Line

To find the normal line on a curve on a specific point, follow the given steps,

  • Determine the derivative of the function to calculate the slope of the tangent on any point
  • Calculate the derivative on the point of interest to get the slope of the tangent line at the point.
  • The normal line slope is the negative reciprocal of the slope of the tangent line. For example, if the slope of the tangent line is m then the slope of the normal line will be -1/m
  • Use the point of interest and the slope to write the equation of the normal line with the help of the point-slope form.
  • Calculate y by rearranging the equation.

How to Find Tangent and Normal Lines

To find the tangent and normal lines on a curve on a specific point, follow the given steps,

  • Determine the derivative of the function to calculate the slope of the tangent line on any point on the curve
  • Now plug in the x coordinate into the derivative and get the slope of the tangent line on that point.
  • Using the point-slope form of the line write the equation of the tangent line,

$$ y - y_1 \;=\; m(x-x_1) $$

  • The normal line slope is the negative reciprocal of the slope of the tangent line
  • Now again use the point slope form with the slope to write the equation of the normal line which is,

$$ y - y_1 \;=\; n(x - x_1) $$

  • Simplify your equation
