Key Calculus Terms and definitions covered in this textbook
• Arccosecant function

See Inverse cosecant function.

• Arithmetic sequence

A sequence {an} in which an = an-1 + d for every integer n ? 2 . The number d is the common difference.

• Coefficient matrix

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

• Conic section (or conic)

A curve obtained by intersecting a double-napped right circular cone with a plane

• Graph of a polar equation

The set of all points in the polar coordinate system corresponding to the ordered pairs (r,?) that are solutions of the polar equation.

• Inverse composition rule

The composition of a one-toone function with its inverse results in the identity function.

• Linear combination of vectors u and v

An expression au + bv , where a and b are real numbers

• Phase shift

See Sinusoid.

An angle in standard position whose terminal side lies on an axis.

• Quartic regression

A procedure for fitting a quartic function to a set of data.

• Random variable

A function that assigns real-number values to the outcomes in a sample space.

• Reference triangle

For an angle ? in standard position, a reference triangle is a triangle formed by the terminal side of angle ?, the x-axis, and a perpendicular dropped from a point on the terminal side to the x-axis. The angle in a reference triangle at the origin is the reference angle

• 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.

• Standard form of a complex number

a + bi, where a and b are real numbers

• Sum of functions

(ƒ + g)(x) = ƒ(x) + g(x)

• Tangent

The function y = tan x

• Vertical line

x = a.

• Weights

See Weighted mean.

• x-intercept

A point that lies on both the graph and the x-axis,.
