    The formula for calculating the projection of a vector onto another vector is this.

projection formula for vector b onto vector a

    The left side of the equation is read, "The projection of vector b onto vector a." The steps for using this formula are demonstrated within the video found in the next section.

    This video reveals what the formula is, provides two examples, and explains the graphical representation.
