The plane passing through the point with normal vector is described by the equation . As for the line, if the equation is multiplied by any nonzero constant k to get the equation kax + kby + kcz = kd, the plane of solutions is the same. A vector is a physical quantity for which both direction and magnitude are defined. The equation of a plane in the three-dimensional space is defined with the normal vector and the known point on the plane. ax + by + cz = d, where at least one of the numbers a, b, c must be nonzero. Equation of a plane. A plane in 3-dimensional space has the equation ax + by + cz + d = 0, where at least one of the coefficients a, b or c must be non-zero. The general equation of a plane is given as: Ax + By + Cz + D = 0 (D ≠ 0) Let us now try to determine the equation of a plane in terms of the intercepts which is formed by the given plane on the respective co-ordinate axes. The equation above is the required equation of the plane that cuts intercepts on three coordinate axes in the Cartesian system. Find the equation of the plane containing the three points P 1 = (1, 0, 1), P 2 = (0, 1, 1), P 3 = (1, 1, 0). Equation of Plane in Different Forms. Let $\vec{n} = (a, b, c)$ be a normal vector to our plane $\Pi$, that is $\Pi \perp \vec{n}$.Instead of using just a single point from the plane, we will instead take a vector that is parallel from the plane. The intercept form of the equation of a plane is where a, b, and c are the x, y, and z intercepts, respectively (all … The standard terminology for the vector N is to call it a normal to the plane. You should check that the three points P. 1, P. 2, P. 3. do, in fact, satisfy this equation. (X − P) = 0 where n → ≠ 0 → is a normal to the plane and where P is a point on the plane, as shown in Figure 9.1. … The normal vector must be perpendicular to the xy-plane, so we can use the direction vector for the z-axis, ~n = h0;0;1i.
