Here you will learn intercept form of a plane equation with examples.<\/p>\n
Let’s begin –<\/p>\n
\nThe equation of a plane intercepting lengths a, b and c with x-axis, y-axis and z-axis respectively is<\/p>\n
\\(x\\over a\\) + \\(y\\over b\\) + \\(z\\over c\\) = 1<\/p>\n<\/blockquote>\n
Note<\/strong> :<\/p>\n
1)<\/strong>. The above equation is known as the intercept form of the plane, because the plane intercepts length a, b and c with x, y and z-axes respectively.<\/p>\n
2)<\/strong>. To determine the intercepts made by a plane with the coordinate axes we proceed as follows :<\/p>\n
For x-intercept : Put y = 0, z = 0 in the equation of the plane and obtain the value of x. The value of x is the intercept on x-axis.<\/p>\n
For y-intercept : Put x = 0, z = 0 in the equation of the plane and obtain the value of y. The value of y is the intercept on y-axis.<\/p>\n
For z-intercept : Put x = 0, y = 0 in the equation of the plane and obtain the value of z. The value of z is the intercept on z-axis.<\/p>\n
Example<\/strong><\/span> : Write the equation of the plane whose intercepts on the coordinates axes are -4, 2 and 3 respectively.<\/p>\n
Solution<\/span><\/strong> : We know that the equation of a plane having a, b and c intercept on the coordinate axes is given by \\(x\\over a\\) + \\(y\\over b\\) + \\(z\\over c\\) = 1<\/p>\n
Here a = -4, b = 2, and c = 3. So ,the equation of the required plane is<\/p>\n
\\(x\\over -4\\) + \\(y\\over 2\\) + \\(z\\over 3\\) = 1 <\/p>\n
\\(\\implies\\) -3x + 6y + 4z =12<\/p>\n\n\n
