What Is A Normal Line Calculator?
Calculus calculations don't have to get you all worked up every day. With this equation of normal line calculator, you can calculate your derivatives with ease and attain top grades in your math homework.
When two lines are perpendicular, their slopes form negative reciprocals. With the normal line equation calculator, this work is simplified for you. All you have to do is key in the required values of the function, and you are good to go!
On top of that, the equation of the normal line calculator gives you the expected graph. You are thus assured of accuracy when submitting your final math paper.
How To Find The Equation of The Normal Line
It's pretty easy to find equation of line normal calculator. The rule for perpendicular lines applies when using the slope of normal line calculator. Note that normal lines are perpendicular to the tangent line when the normal intersects with the curve.
Therefore, the slope of each normal line and corresponding tangent are opposite to each other. You will find this with a derivative.
The line's equation, normal to the curve, is derived as follows:
Since the slope's tangent line is m=f′(x), then the slope of the normal line is m=−1/f′(x)
Equation Of Normal Line at Point Calculator – Examples
1. Find the normal line equation to the graph of f(x) = at the point (−1, 2).
y - y1 = m(x – x1)
y – 2 = 2 (x+1)
y – 2 = 2x + 2
2x - y = -4
2. Calculate the equation of the tangent line to the graph of f(x) = √(x2+3) at the point (−1, 2).
y - y1 = m(x – x1)
y – 2 = -1/2 (x+1)
2y – 4 = -x -1
x + 2y = 3
