9 Vectors and Oblique Triangles
LEARNING OUTCOMES
After completion of this chapter, the student should be able to:
Distinguish between a scalar and a vector
Add vectors graphically by the polygon method and the parallelogram method
Resolve a vector into its x- and y-components
Add vectors by components
Solve application problems involving vectors
Solve oblique triangles using the law of sines and/or the law of cosines
Solve application problems involving oblique triangles
In many applications, we often deal with such things as forces and velocities.
To study them, both their magnitudes and directions must be known. In general, a quantity for which we must specify both magnitude and direction is called a vector.
In basic applications, a vector ...
