13.1.12 With the attached image, please help me find proj u and scal u.

The text in the image reads: "Find proj<sub>v</sub>u and scal<sub>v</sub>u by inspection without using formulas." **Explanation:** The text refers to a mathematical task involving vectors. It asks the reader to find the projection (proj) and the scalar component (scal) of a vector **u** onto another vector **v** by visual or intuitive inspection rather than calculating it with formulas. This exercise is typically aimed at deepening understanding of vector components in geometry or physics, fostering an intuitive grasp of vector interactions. No graphs or diagrams are present to provide additional context.

The image presents a Cartesian coordinate system with vectors \( \mathbf{u} \) and \( \mathbf{v} \) illustrated. 1. **Axes:** - The horizontal axis is labeled as \( x \). - The vertical axis is labeled as \( y \). - Both axes range from -10 to 10. 2. **Vectors:** - **Vector \( \mathbf{u} \):** - Represented by a blue arrow. - Starts at the origin (0,0) and points towards (4,2). - This indicates that vector \( \mathbf{u} \) has components (4,2). - **Vector \( \mathbf{v} \):** - Represented by a purple arrow. - Starts at the origin (0,0) and points towards (0, -2). - This suggests that vector \( \mathbf{v} \) has components (0,-2). 3. **Gridlines:** - The graph is overlaid with a grid, with each square representing a unit distance of 1 on both axes. The visualization helps in understanding vector representation, components, and their direction in a two-dimensional plane.
