# What is Vector Equation?

## What is Vector Equation? Do you really want to know the exact equation of a vector? Is it difficult to find out the equation of a vector? What formulas you can use to find out the equation of a vector? These are some of the questions that will take place in your mind when you have to find out the vector equation. First of all, you have to be calm and composed so that you can understand how easily you can find out the equation of a vector. You can go through the following paragraph where you will find the required information about the vector equation.

Most of the times, two types of vector equations can be used in which the first equation is the vector equation of a line in and another one is the vector equation of a plane.

### Vector equations

In order to find out the equation on and solve the questions, you will have to become familiar with the different equation formats of both these equations. What is vector equation? Let’s check out vector equation of a line as well as the vector equation of a plane:

### Vector equation of a line

In the beginning, you need to know that a line will always be determined by a direction and point. This is why you always need to find the required equation of a line in three dimensions. In a situation, you can take a point A on the line and non-zero vector B parallel to the same line. The vector equation of a line is a special equation which is completely satisfied by the vector that has its top at a point of the line.

``                            r̂= â+λb̂``

### Vector equation of a plane

The Vector Equation of a Plane is a normal vector to the XY. Any three different points describe the plane, or otherwise, a distinct point in the plane and a specified normal vector to the plane. As you already know, a plane can be described in different ways so it can be difficult for you to find the equation of a vector of a plane. Let us assume a point is given as p0.

Next, let a unique line goes through p0. The drawn line will be known as the normal to the play in p0. Any particular vector Where n is not equal to zero will be known as the normal vector of the plane.

On the other hand, when the point P lies the plane via p0 perpendicular to if and only if and n are free perpendicular. If this is a situation, the vector equation can be denoted as the following form:

``                              (r-r0).n= 0``

Now, you may have successfully collected information about what is vector equation. Make sure that you will use reliable methods and tactics when it comes to solving the vector equation in a plane as well as in a line.

Both vector equation of a plane and a line can be used for various purposes. Now, you can have the rest of the benefits with the available information regarding the vector equation.
