Formula Used in “Line of Intersection of Two Planes Calculator”
The line of intersection of two planes can be calculated using a systematic mathematical approach. The standard formula to determine the line of intersection of two planes given by:
Plane 1: (a_1x + b_1y + c_1z + d_1 = 0)
Plane 2: (a_2x + b_2y + c_2z + d_2 = 0)
The direction vector ( mathbf{d} ) of the line of intersection can be found using the cross product of the normal vectors of the planes:
Direction Vector: ( mathbf{d} = mathbf{n_1} times mathbf{n_2} )
where
( mathbf{n_1} = (a_1, b_1, c_1) )
( mathbf{n_2} = (a_2, b_2, c_2) )
The line can be expressed in symmetric form as:
Equation of the Line: (frac{x – x_0}{d_x} = frac{y – y_0}{d_y} = frac{z – z_0}{d_z})
Step-by-Step Breakdown of the Formula
The process of calculating the line of intersection of two planes involves several clear steps. Below is a breakdown of the required calculations:
- Identify the Plane Equations: Start with the plane equations provided in the standard form.
- Extract Normal Vectors: From the plane equations, identify the coefficients which make up the normal vectors:
- ( mathbf{n_1} = (a_1, b_1, c_1) )
- ( mathbf{n_2} = (a_2, b_2, c_2) )
- Calculate the Cross Product: Compute the direction vector ( mathbf{d} ) using the cross product:
- ( mathbf{d} = mathbf{n_1} times mathbf{n_2} )
- Find a Point on the Line: Insert appropriate values from the plane equations to find coordinates ((x_0, y_0, z_0)) that satisfy both plane equations.

Example Calculation
To illustrate how to utilize the “Line of Intersection of Two Planes Calculator”, let’s go through a practical example:
Consider the following two planes:
Plane 1: (2x + 3y – z + 5 = 0)
Plane 2: (4x – 2y + 5z – 7 = 0)
Step 1: Identify the Normal Vectors
The normal vectors for the two planes are:
- ( mathbf{n_1} = (2, 3, -1) )
- ( mathbf{n_2} = (4, -2, 5) )
Step 2: Calculate the Direction Vector
Using the cross product:
( mathbf{d} = mathbf{n_1} times mathbf{n_2} )
| Calculation | Result |
|---|---|
| (d_x = (3)(5) – (-1)(-2) = 15 – 2 = 13) | 13 |
| (d_y = -((2)(5) – (-1)(4)) = -(10 + 4) = -14) | -14 |
| (d_z = (2)(-2) – (3)(4) = -4 – 12 = -16) | -16 |
Step 3: Find a Point on the Line
To find a point ((x_0, y_0, z_0)) that satisfies both planes, set (z = 0) and solve:
From Plane 1: (2x + 3y + 5 = 0 Rightarrow y = -frac{2}{3}x – frac{5}{3})
From Plane 2: (4x – 2y – 7 = 0 Rightarrow y = 2x – frac{7}{2})
Equating these gives (2x – frac{7}{2} = -frac{2}{3}x – frac{5}{3}). Solving yields (x = 1), (y = -frac{9}{3}), (z = 0). Thus, ((1, -3, 0)) is a point on the line.
Step 4: Formulate the Symmetric Equation
Substituting the point and direction vector into the symmetric equation:
Line: (frac{x – 1}{13} = frac{y + 3}{-14} = frac{z – 0}{-16})
