Equation Of The Tangent Plane Calculator







 

Introduction

Are you looking to calculate the equation of a tangent plane for a given function at a specific point? The Tangent Plane Calculator can help you determine the equation of the tangent plane, the z-coordinate of the point on the tangent plane, the value of the function at that point, and more. In this guide, we’ll walk you through how to use this calculator, the formula behind it, provide an example, and answer some frequently asked questions.

How to Use

Using the Tangent Plane Calculator is straightforward:

  1. Input the following values:
    • z-coordinate of the point on the tangent plane.
    • Value of the function at the point (x0, y0).
    • Partial derivative of the function with respect to x at the point (x0, y0).
    • Partial derivative of the function with respect to y at the point (x0, y0).
    • Difference between the x-coordinate of a point on the tangent plane and the x-coordinate of the point of tangency (x0).
    • Difference between the y-coordinate of a point on the tangent plane and the y-coordinate of the point of tangency (y0).
  2. Use the formula provided to calculate the equation of the tangent plane:
    z = f(x0, y0) + fx(x0, y0)(x – x0) + fy(x0, y0)(y – y0)
  3. Create a clickable button within a form for easy calculation.

Formula

The formula to calculate the equation of the tangent plane is as follows:

z = f(x0, y0) + fx(x0, y0)(x – x0) + fy(x0, y0)(y – y0)

Where:

  • z is the z-coordinate of the point on the tangent plane.
  • f(x0, y0) is the value of the function at the point (x0, y0).
  • fx(x0, y0) is the partial derivative of the function with respect to x at the point (x0, y0).
  • fy(x0, y0) is the partial derivative of the function with respect to y at the point (x0, y0).
  • (x0, y0) are the coordinates of the point of tangency.

Example

Let’s illustrate the usage of the Tangent Plane Calculator with an example. Suppose:

  • z-coordinate of the point on the tangent plane = 5.
  • Value of the function at the point (x0, y0) = 10.
  • Partial derivative of the function with respect to x at the point (x0, y0) = 2.
  • Partial derivative of the function with respect to y at the point (x0, y0) = 3.
  • Difference between x-coordinate of a point on the tangent plane and x-coordinate of the point of tangency (x0) = 1.
  • Difference between y-coordinate of a point on the tangent plane and y-coordinate of the point of tangency (y0) = 2.

Using the formula, we calculate:

z = 10 + 2(x – 1) + 3(y – 2)
