## How do you find the coordinate of a vector?

To determine the coordinates of a vector a in the plane, the first step is to translate the vector so that its tail is at the origin of the coordinate system. Then, the head of the vector will be at some point (a1,a2) in the plane. We call (a1,a2) the coordinates or the components of the vector a.

### What is a coordinate vector field?

In vector calculus and physics, a vector field is an assignment of a vector to each point in a subset of space. In coordinates, a vector field on a domain in n-dimensional Euclidean space can be represented as a vector-valued function that associates an n-tuple of real numbers to each point of the domain.

#### What is the difference between coordinate and vector?

To interpret a vector, we basically need other vectors that will tell us how to interpret each of the numbers. If you want to define a coordinate system (something that tell us how to interpret a point) in two dimensions, we need two basis vectors and an origin.

**What is a vector point?**

A Point has position in space. A Vector has both magnitude and direction, but no fixed position in space. Geometrically, we draw points as dots and vectors as line segments with arrows. We will generally draw vectors by attaching them to a specific point, but it should be emphasized that any vector is positionless.

**How do you add coordinates to a vector?**

To add the two vectors, add them in coordinate form: (3.5, 3.5) + (5.7, 4.0) = (9.2, 7.5). Convert (9.2, 7.5) into magnitude/angle form. Apply the equation theta = tan–1(y/x) to find the angle, which is tan–1(7.5/9.2) = tan–1(0.82) = 39 degrees. Converting to two significant digits gives you 12.

## Can a constant vector define a vector field?

To every scalar field s(x,y) there corresponds a ‘constant’ vector field x = A s(x,y) and y = B s(x,y), where A,B are direction cosines. The vector field is only partially constant since only the directions, and not the magnitudes, which are equal to |f(x,y)|, of the field vectors are constant.

### How do you add coordinate vectors?

#### Can you add a point and a vector?

We have already seen that the difference between two points can be considered as a vector. However, in general, it makes no sense to add two points together.

**What happens when you add a vector to a zero vector?**

A zero vector, also known as a null vector, is a vector that has an arbitrary direction and has no magnitude. When a vector is added to a zero vector, the resulting vector is the same as the vector that was added to the zero vector.

**How do you write a position vector?**

Position Vector Formula

- The formula to determine the position vector from A to B is AB = (xk+1 – xk, yk+1 – yk).
- The position vector AB refers to a vector that starts at point A and ends at point B.

## Is a coordinate system a requirement for a vector space?

However, the vector space structure doesn’t include one particular specified coordinate system. In other words, to define a finite dimensional vector space, you don’t need to specify a coordinate system, but you can always find one if you want.

### Are vectors truly independent of coordinate systems?

While a vector is an objective quantity, meaning its identity is independent of any coordinate system, the components of a vector depend on what basis the vector is represented in.

#### What are vector and polar coordinates?

The two polar coordinates of a point in a plane may be considered as a two dimensional vector. Such a polar vector consists of a magnitude (or length) and a direction (or angle). The magnitude, typically represented as r , is the distance from a starting point, the origin , to the point which is represented.

**What is the Cartesian form of a vector?**

The general form of any vector in the Cartesian coordinate system is as follows-A x is the x-component, A y is the y-component and A z is the z-component of given vector.
