I don't think I get this that I have to scale it correctly...
A unit vector is a vector that has a magnitude of 1 and points in a specific direction. It is commonly used in mathematics and physics to represent the direction of a vector without considering its magnitude.
The magnitude of a vector is equal to the square root of the sum of the squares of its components. In this case, the magnitude of the given vector is √(5² + 1² + (-3)²) = √35.
Two vectors are parallel if they have the same or opposite direction. In other words, their direction vectors are scalar multiples of each other. Geometrically, parallel vectors lie on the same line or are parallel to each other.
To find a unit vector parallel to a given vector, you first need to find the magnitude of the vector. Then, divide each component of the vector by its magnitude. The resulting vector will have a magnitude of 1 and will be parallel to the given vector.
Yes, a vector can have an infinite number of unit vectors parallel to it. This is because you can multiply the unit vector by any non-zero scalar and still get a vector with a magnitude of 1 and parallel to the given vector.
