What function do you use to find the angle of a vector, when you know its components?

Step-by-step explanation:

If we are given components of a vector then we can find the angle between them.

Suppose we are given a vector v

Where x is the horizontal component and y is the vertical component.

The angle can be found by using

The magnitude of the vector v can be found using

Example:

Lets do a quick example:

The angle of the vector is

The magnitude of the vector is

.25
