### What is a Normal Line

The normal line is a geometrical concept. It refers to a line that is perpendicular, or normal to the curve or another line on a point. It specifically refers to the curve on a point that is perpendicular to the tangent line.

The normal line gives information about the behavior of a curve on a point. It helps to calculate the direction of the maximum rate of change or slope that is perpendicular to the curve on a point, also be calculated with the help of the equation of the line calculator.

### How to Find Normal Line

You should be wondering how to find normal line. To find the normal line, you have to follow some simple steps that are,

• Start by finding the slope of the tangent line on a point. To do this, take the derivative of the function presenting the curve and find it on the point. The tangent line slope is equal to the value of the derivative on a point.
• Now calculate the negative reciprocal of the tangent line of slope.
• Use the point-slope form with the normal line and the point to write the equation of the normal line
• Now simplify the equation and verify it whether it represents a line perpendicular to the curve on the point or not.

### How to Find Tangent and Normal Lines

In order to find the tangent and normal line the tangent line finder suggests following the given steps,

• Begin with the equation of the parametric representation of the curve
• Identify the point you want to determine the tangent and normal line
• Find the derivative representing the curve with respect to the independent variable. Calculate both derivatives of x and y if the curve is given parametrically.
• Replace the x coordinate with the derivative expression
• Now calculate the slope of the tangent line of the derivative on a point
• Calculate the normal line slope that is the negative reciprocal of the slope of tangent line
• Now write the equation of both tangent and normal line
