How Vector Projection Calculator works
Find the vector projection of the first 3D vector onto the second.
The target vector must be nonzero. Uses dot(a,b) / dot(b,b) × b. Finite real inputs; output uses up to 12 significant digits. Floating-point results may be rounded.
How to use Vector Projection Calculator
