WebIf we are given a point that lies on the plane, (𝑥, 𝑦, 𝑧) , and two nonparallel vectors, ⃑ 𝑣 and ⃑ 𝑣 , that are parallel to the plane, then we can determine the normal to the plane from these two vectors. Since the vectors are both parallel to the plane, the normal vector must be perpendicular to both ⃑ 𝑣 and ⃑ 𝑣 . WebNov 16, 2024 · This is called the scalar equation of plane. Often this will be written as, ax+by +cz = d a x + b y + c z = d. where d = ax0 +by0 +cz0 d = a x 0 + b y 0 + c z 0. This second form is often how we are given equations of planes. Notice that if we are given the equation of a plane in this form we can quickly get a normal vector for the plane.
