the vector $\displaystyle \vec{a}=(2,3)$ is projected onto the x=axis. what is the scalar projection? what is the vector projection?
what are the scalar and vector projections when $\displaystyle \vec{a}$ is projected onto the y-axis
Have you thought about these at all yourself? These problems are about as trivial as you going to see! Draw a picture. What does the projection of (2, 3) onto the x-axis look like?
