Additive inverse of a complex number
The opposite of a + bi, or a  bi

Amplitude
See Sinusoid.

Angle
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)

Common difference
See Arithmetic sequence.

Difference of functions
(ƒ  g)(x) = ƒ(x)  g(x)

Discriminant
For the equation ax 2 + bx + c, the expression b2  4ac; for the equation Ax2 + Bxy + Cy2 + Dx + Ey + F = 0, the expression B2  4AC

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

Frequency
Reciprocal of the period of a sinusoid.

Graph of an equation in x and y
The set of all points in the coordinate plane corresponding to the pairs x, y that are solutions of the equation.

Halfplane
The graph of the linear inequality y ? ax + b, y > ax + b y ? ax + b, or y < ax + b.

Hypotenuse
Side opposite the right angle in a right triangle.

Lefthand limit of f at x a
The limit of ƒ as x approaches a from the left.

Normal distribution
A distribution of data shaped like the normal curve.

Parametric curve
The graph of parametric equations.

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

Quartile
The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

Rational zeros theorem
A procedure for finding the possible rational zeros of a polynomial.

Second quartile
See Quartile.

Solution of an equation or inequality
A value of the variable (or values of the variables) for which the equation or inequality is true

Standard form of a complex number
a + bi, where a and b are real numbers
