g ? 32 ft/sec2 ? 9.8 m/sec

• Algebraic model

An equation that relates variable quantities associated with phenomena being studied

• Angle between vectors

The angle formed by two nonzero vectors sharing a common initial point

• Endpoint of an interval

A real number that represents one “end” of an interval.

• Equal complex numbers

Complex numbers whose real parts are equal and whose imaginary parts are equal.

• Infinite limit

A special case of a limit that does not exist.

• Interval

Connected subset of the real number line with at least two points, p. 4.

• Inverse relation (of the relation R)

A relation that consists of all ordered pairs b, a for which a, b belongs to R.

• Local maximum
