Direction of the Vector Calculator
The Direction of the Vector Calculator is a tool designed to compute unit vectors and vectors of specific magnitudes in both 2D and 3D space. A unit vector points in the direction of the original vector and has a magnitude of one, while a scaled vector maintains the direction but has a different magnitude. This calculator simplifies the process of finding these vectors, providing precise results along with visual aids to enhance understanding.
How to Use the Calculator
Select the dimension (2D or 3D) for your vector calculation. Enter the components of the vector (x, y for 2D; x, y, z for 3D) and specify a desired magnitude if applicable. Click "Calculate" to view the results, including unit vectors and scaled vectors. The results will be displayed in a table format and visualized with a bar chart. Use the "Clear" button to reset all fields and start a new calculation.

FAQ
What is a unit vector?
A unit vector is a vector with a magnitude of one that points in the direction of a given vector. It is used to describe direction without regard to magnitude.
How do I calculate a unit vector in 2D?
To find a unit vector in 2D, calculate the magnitude of the vector and then divide each component by this magnitude. The unit vector will have a magnitude of 1 and point in the same direction as the original vector.
How do I find a vector of a specific magnitude in 2D?
First, find the unit vector of the original vector. Then, multiply the unit vector by the desired magnitude to obtain the scaled vector in the direction of the original vector.
What if I only have one component of a 3D vector?
If only one component is known, you cannot determine a unique vector direction in 3D space. More components are required to fully describe the vector direction.
Can this calculator handle complex numbers?
No, this calculator is designed for real-valued vectors in 2D and 3D space. Complex numbers require different methods for vector calculations.
What is the difference between magnitude and direction?
Magnitude is the length of the vector, while direction describes which way the vector points. The unit vector represents direction only, with a magnitude of one.
How accurate is the calculator?
The calculator provides accurate results based on the input values. Ensure that the values entered are correct to obtain precise results.
