Coefficient matrix
A matrix whose elements are the coefficients in a system of linear equations

Complex number
An expression a + bi, where a (the real part) and b (the imaginary part) are real numbers

Implicitly defined function
A function that is a subset of a relation defined by an equation in x and y.

Inverse sine function
The function y = sin1 x

Limit
limx:aƒ1x2 = L means that ƒ(x) gets arbitrarily close to L as x gets arbitrarily close (but not equal) to a

Midpoint (in a coordinate plane)
For the line segment with endpoints (a,b) and (c,d), (aa + c2 ,b + d2)

NDER ƒ(a)
See Numerical derivative of ƒ at x = a.

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

Polar equation
An equation in r and ?.

Resistant measure
A statistical measure that does not change much in response to outliers.

Richter scale
A logarithmic scale used in measuring the intensity of an earthquake.

Rigid transformation
A transformation that leaves the basic shape of a graph unchanged.

Sample standard deviation
The standard deviation computed using only a sample of the entire population.

Slant line
A line that is neither horizontal nor vertical

Standard position (angle)
An angle positioned on a rectangular coordinate system with its vertex at the origin and its initial side on the positive xaxis

Sum of a finite arithmetic series
Sn = na a1 + a2 2 b = n 2 32a1 + 1n  12d4,

Sum of functions
(ƒ + g)(x) = ƒ(x) + g(x)

Upper bound for real zeros
A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.

Variance
The square of the standard deviation.

Vector equation for a line in space
The line through P0(x 0, y0, z0) in the direction of the nonzero vector V = <a, b, c> has vector equation r = r0 + tv , where r = <x,y,z>.
