Angle of elevation
The acute angle formed by the line of sight (upward) and the horizontal

Arrow
The notation PQ denoting the directed line segment with initial point P and terminal point Q.

Average velocity
The change in position divided by the change in time.

Convergence of a sequence
A sequence {an} converges to a if limn: q an = a

Exponential function
A function of the form ƒ(x) = a ? bx,where ?0, b > 0 b ?1

Exponential regression
A procedure for fitting an exponential function to a set of data.

Fivenumber summary
The minimum, first quartile, median, third quartile, and maximum of a data set.

Infinite discontinuity at x = a
limx:a + x a ƒ(x) = q6 or limx:a  ƒ(x) = q.

Integers
The numbers . . ., 3, 2, 1, 0,1,2,...2

Magnitude of a vector
The magnitude of <a, b> is 2a2 + b2. The magnitude of <a, b, c> is 2a2 + b2 + c2

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

Opens upward or downward
A parabola y = ax 2 + bx + c opens upward if a > 0 and opens downward if a < 0.

Origin
The number zero on a number line, or the point where the x and yaxes cross in the Cartesian coordinate system, or the point where the x, y, and zaxes cross in Cartesian threedimensional space

Parallel lines
Two lines that are both vertical or have equal slopes.

Polar coordinates
The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

Row echelon form
A matrix in which rows consisting of all 0’s occur only at the bottom of the matrix, the first nonzero entry in any row with nonzero entries is 1, and the leading 1’s move to the right as we move down the rows.

Scientific notation
A positive number written as c x 10m, where 1 ? c < 10 and m is an integer.

Sum of two vectors
<u1, u2> + <v1, v2> = <u1 + v1, u2 + v2> <u1 + v1, u2 + v2, u3 + v3>
