Dot Product Calculator
Compute the dot product of two vectors in any dimension. Get the component working, both lengths, the cosine, the angle in degrees and an orthogonality verdict.
Cross Product Calculator
Compute a × b for two 3D vectors. Get all three components, the magnitude as a parallelogram area, the triangle area, the unit normal and the angle between them.
Angle Between Two Vectors Calculator
Find the angle between two vectors in degrees and radians from their components. Shows the dot product, both magnitudes, cos theta and the line angle.
Vector Projection Calculator
Resolve one vector along another. Get the vector projection, the signed scalar component, the orthogonal remainder and a Pythagoras check, with every step shown.
