Precalculus: Mathematics for Calculus (Standalone Book) 7th Edition - Solutions by Chapter

A triangle in which all angles measure less than 90°

Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

The change in position divided by the change in time.

<u1, u2> - <v1, v2> = <u1 - v1, u2 - v2> or <u1, u2, u3> - <v1, v2, v3> = <u1 - v1, u2 - v2, u3 - v3>

A polynomial that the function approaches as.

Systems of equations that have the same solution.

Vectors with the same magnitude and direction.

The terms of the Fibonacci sequence.

A logarithm with base e.

Length of 1 minute of arc along the Earth’s equator.

See Sequence of partial sums.

A coordinate system whose ordered pair is based on the directed distance from a central point (the pole) and the angle measured from a ray from the pole (the polar axis)

See Power function

Behavior that is determined only by the laws of probability.

The function y = sec x.

The distance from the center to a vertex of an ellipse.

A finite or infinite sum of terms.
