Simply by looking at the equation of a plane you can determine a vector that is normal (i.e. orthogonalperpendicular90 degree angle) to a plane. What I want to do in this vector is make sure that were good at picking out what the normal vector to a plane is if we are given the equation for a plane. Unit Normal Vector. A unit vector is a vector of vectorgth 1. Any nonzero vector can be divided by its vectorgth to form a unit vector. Thus for a plane (or a line) a normal vector can be divided by its vectorgth to get a unit normal vector.

In geometry a normal is an object such as a line or vector that is perpendicular to a given object. For example in two dimensions the normal line to a curve at a given point is the line perpendicular to the tangent line to the curve at the point. Matrices vectors vector vectores transformations eigenvectorsvalues all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or Best Answer To get the normal vector to the plane all you must do is grab the coefficients of each variable when in standard form (i.e. when written in expanded form as you have with all variable terms opposite the non-variable term) and place them as the components of the vector.

Lets take a little bit of a hiatus from our more rigorous math where were building the mathematics of vector algebra and just think a little bit about something that youll probably encounter if you ever have to have to write a three-dimensional computer program or have to do any mathematics dealing with three dimensions. Take one point as the base point compute the two difference vectors to the other two points (those two span the plane) and take their cross product to get a normal vector. In practice its usually easier to work out bf n in a given example rather than try to set up some general equation for the plane. ## Constructing A Unit Normal Vector To A Surface
