Key Calculus Terms and definitions covered in this textbook
• Additive identity for the complex numbers

0 + 0i is the complex number zero

• Anchor

See Mathematical induction.

• Arccosecant function

See Inverse cosecant function.

• Arccotangent function

See Inverse cotangent function.

• Direction angle of a vector

The angle that the vector makes with the positive x-axis

• Elementary row operations

The following three row operations: Multiply all elements of a row by a nonzero constant; interchange two rows; and add a multiple of one row to another row

• Exponent

See nth power of a.

• Exponential decay function

Decay modeled by ƒ(x) = a ? bx, a > 0 with 0 < b < 1.

• Feasible points

Points that satisfy the constraints in a linear programming problem.

• Focal length of a parabola

The directed distance from the vertex to the focus.

• Hyperbola

A set of points in a plane, the absolute value of the difference of whose distances from two fixed points (the foci) is a constant.

• Implied domain

The domain of a function’s algebraic expression.

• Intercepted arc

Arc of a circle between the initial side and terminal side of a central angle.

• Inverse function

The inverse relation of a one-to-one function.

• Logistic growth function

A model of population growth: ƒ1x2 = c 1 + a # bx or ƒ1x2 = c1 + ae-kx, where a, b, c, and k are positive with b < 1. c is the limit to growth

• LRAM

A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the left-hand endpoint of each subinterval

• Parametrization

A set of parametric equations for a curve.

• Pseudo-random numbers

Computer-generated numbers that can be used to approximate true randomness in scientific studies. Since they depend on iterative computer algorithms, they are not truly random

Any one of the four parts into which a plane is divided by the perpendicular coordinate axes.

• Replication

The principle of experimental design that minimizes the effects of chance variation by repeating the experiment multiple times.
