Knowledge
Students know:
- The difference between a ray and a directed line segment.
- When drawing a vector on the xy-plane, magnitude is represented by a distance.
Skills
Students are able to:
- Locate vectors on the xy-plane.
- Use the unit circle to find trigonometric ratios for values in all four quadrants.
- Use the Pythagorean Theorem to find the lengths of sides of a right triangle.
Understanding
Students understand that:
- Magnitude as the length of a vector and direction of a vector as the measure of the angle it makes with a horizontal line
- When vectors are represented in component form, ensuing computations and applications can be accomplished.
