Can I use this for 2D vectors?
The cross product in this calculator is defined for 3D vectors. Extend 2D vectors by adding a zero z-component if needed.

Use this companion guide beside the interactive calculator to make sure you understand the “why” behind every click. Each section includes the classroom explanation, student-friendly language, and quick practice prompts.
Before you start
Collect the data points listed below and double-check their units. Keeping an organized “givens” list is one of the fastest ways to reduce math errors and impress exam graders.
- cross product
- vector product
- orthogonal vector
Detailed procedure
Step 1
Enter two 3-component vectors.
Step 2
Confirm the components correspond to x, y, and z values.
Step 3
Review the cross product vector and its magnitude.
Teaching & troubleshooting tips
What if my vectors are parallel?
Parallel vectors produce a zero vector because they have no perpendicular component.
