PreCalculus Semester 1 Practice Exam (Chapter 6 Content)

Front

What does it mean for two vectors to be orthogonal?

Back

Two vectors are orthogonal if their dot product is zero.

Front

What does it mean for two vectors to be parallel?

Back

Two vectors are parallel if they have the same or opposite direction, which can be determined if one vector is a scalar multiple of the other.

Front

How do you determine the distance between two points given their bearings?

Back

Use trigonometric functions to resolve the bearings into components and apply the distance formula.

Front

What is the significance of bearings in navigation?

Back

Bearings are used to describe the direction of one point from another, measured in degrees from the north.

Front

What is the relationship between the sides and angles in a triangle?

Back

In any triangle, larger angles are opposite longer sides, and smaller angles are opposite shorter sides.
