Key Calculus Terms and definitions covered in this textbook
  • Blind experiment

    An experiment in which subjects do not know if they have been given an active treatment or a placebo

  • Coefficient matrix

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

  • Complex conjugates

    Complex numbers a + bi and a - bi

  • Complex fraction

    See Compound fraction.

  • Component form of a vector

    If a vector’s representative in standard position has a terminal point (a,b) (or (a, b, c)) , then (a,b) (or (a, b, c)) is the component form of the vector, and a and b are the horizontal and vertical components of the vector (or a, b, and c are the x-, y-, and z-components of the vector, respectively)

  • Factor

    In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

  • Finite series

    Sum of a finite number of terms.

  • Inverse cosine function

    The function y = cos-1 x

  • Linear inequality in two variables x and y

    An inequality that can be written in one of the following forms: y 6 mx + b, y … mx + b, y 7 mx + b, or y Ú mx + b with m Z 0

  • Negative linear correlation

    See Linear correlation.

  • Permutation

    An arrangement of elements of a set, in which order is important.

  • Permutations of n objects taken r at a time

    There are nPr = n!1n - r2! such permutations

  • Plane in Cartesian space

    The graph of Ax + By + Cz + D = 0, where A, B, and C are not all zero.

  • Projection of u onto v

    The vector projv u = au # vƒvƒb2v

  • Quartic regression

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

  • Symmetric about the y-axis

    A graph in which (-x, y) is on the graph whenever (x, y) is; or a graph in which (-r, -?) or (r, ?, -?) is on the graph whenever (r, ?) is

  • Symmetric property of equality

    If a = b, then b = a

  • Terminal side of an angle

    See Angle.

  • Unit vector

    Vector of length 1.

  • Unit vector in the direction of a vector

    A unit vector that has the same direction as the given vector.
