Linear Algebra
Vector Magnitude Calculator
Compute the Euclidean magnitude (length) of a 3D vector as √(x² + y² + z²). Use it to normalise a vector, measure distance, or check the size of a direction vector.
Fill in the required fields to see your result.
Linear Algebra
Vector Dot Product Calculator
Compute the dot product of two 3D vectors as v1·v2 = v1x·v2x + v1y·v2y + v1z·v2z. Use it to measure projection, test orthogonality, or compute angles via the cosine formula.
