Vector Projection Calculator is a free online tool that displays the vector projection for the given two vectors. Here we need to calculate the inverse of the projection, so to include the vector direction in the calculation, we separate the scalar from the unit vector. Projection[u, v, f] finds projections with respect to the inner product function f .
