Vector Operations:
From: | To: |
Vector operations are mathematical operations performed on vectors, which are quantities that have both magnitude and direction. Common operations include addition, subtraction, and dot product.
The calculator performs the following vector operations:
Where:
Explanation: Vector addition combines vectors tip-to-tail, subtraction finds the difference between vectors, and dot product calculates a scalar value representing their alignment.
Details: Vector operations are fundamental in physics, engineering, computer graphics, and machine learning. They're used in force calculations, 3D modeling, and data analysis.
Tips: Enter the x, y, z components of both vectors, select the operation type, and click Calculate. Results are shown in component form for addition/subtraction, or as a scalar for dot product.
Q1: What's the difference between dot product and cross product?
A: Dot product gives a scalar value, while cross product gives a vector perpendicular to both input vectors.
Q2: Can I perform operations on 2D vectors?
A: Yes, just set the z-component to 0 for both vectors.
Q3: What does a dot product of 0 mean?
A: It means the vectors are perpendicular (90° angle between them).
Q4: How is vector addition different from scalar addition?
A: Vector addition combines both magnitude and direction, while scalar addition just sums numbers.
Q5: What are unit vectors?
A: Vectors with magnitude 1, often used as basis vectors (i, j, k in 3D space).
