Introduction to normal line calculator with steps
Normal line equation calculator is an online tool used to calculate the derivative of the normal line. It uses the normal line equation and the slope formula to calculate the equation. In other words, it is used to calculate the line perpendicular to the tangent line at the given point.
In mathematics, the derivative has many applications such that it can be used to find the tangent line of a function and its slope. So we introduce slope of normal line calculator that can handle any function to calculate its normal line.
Formula used by normal line and tangent line calculator
This equation of the normal line calculator is used to find the normal line equation using tangent at a given point. It uses following step-by-step formulas to calculate the equation:
- It calculates the value of the function at the given point by putting:
- $$ x \;=\; x_o $$
So,
$$ f(x_o) \;=\; y_o $$ - It calculates the slope M of the normal line at:
- $$ x \;=\; x_o $$
by using this formula:
$$ M(x_o) \;=\; - \frac{1}{f'(x_o)} $$ - The general form of the equation of tangent passing through:
- $$ (x_o \;,\; y_o) $$
And having slope M is:
$$ (y \;-\; y_o) \;=\; m(x \;-\; x_o) $$
The normal line calculator uses this formula to calculate normal line equation using slope M, given point pf:
$$ x\;=\; x_o $$
And the value of function at the given point of:
$$ y_o $$
How to use slope of normal line calculator?

Why use a normal line equation calculator?
The tangent is the straight line that touches the given curve at a given point. And the normal line is perpendicular to the tangent. So we can say that the normal line is associated with the deviation at a given point. While computing the normal line equation, students may get stuck with this method.
It would be best to use the normal line finder because it provides you with the step-by-step process and the graph as a visual representation of the given curve.
Benefits of using equation of the normal line calculator with steps
In geometry, you can only be an expert in calculations if you practice. The equation of normal line calculator helps you practice with many different curves. Some other benefits of this tool are:
- It clarifies the result with the graph by showing where the point x touches the given curve and the tangent to the curve.
- It is reliable because it never gives false results.
- It can save your time by giving the result with every defined step.
- You can practice with unlimited examples for free by using this tool to find the equation of a normal line.
- Normal line equation calculator can handle any curve like parabola, ellipse, and hyperbola, making it more beneficial for students.
How to find the equation of a normal line?
Consider a curve given as:
$$ y \;=\; 4x^2 $$
We have to find the normal line at the point of:
$$ x_o \;=\; 1 $$
So, the value of the given function at this point is,
$$ y_o \;=\; 4(1)^2 \;=\; 4 $$
And the slope can be found by,
$$ M(x_o) \;=\; - \frac{1}{f'(x_o)} $$
Here,
$$ f'(x_o) \;=\; 8 $$
So,
$$ M(x_o) \;=\; - \frac{1}{8} $$
The point slope form of the equation is,
$$ (y \;-\; y_o) \;=\; M(x \;-\; x_o) $$
So, the equation of normal line at (1, 4) can be calculated as,
$$ (y \;-\; 4) \;=\; -\; \frac{1}{8} (x \;-\; 1) $$ $$ y \;=\; -\; \frac{x}{8} \;+\; \frac{1}{8} \;+\; 4 $$ $$ y \;=\; -\; \frac{x}{8} \;+\; \frac{33}{8} $$
