Key Calculus Terms and definitions covered in this textbook
  • Circular functions

    Trigonometric functions when applied to real numbers are circular functions

  • Compounded annually

    See Compounded k times per year.

  • Constant

    A letter or symbol that stands for a specific number,

  • Distance (in a coordinate plane)

    The distance d(P, Q) between P(x, y) and Q(x, y) d(P, Q) = 2(x 1 - x 2)2 + (y1 - y2)2

  • DMS measure

    The measure of an angle in degrees, minutes, and seconds

  • Expanded form

    The right side of u(v + w) = uv + uw.

  • 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.

  • Geometric sequence

    A sequence {an}in which an = an-1.r for every positive integer n ? 2. The nonzero number r is called the common ratio.

  • Half-life

    The amount of time required for half of a radioactive substance to decay.

  • Histogram

    A graph that visually represents the information in a frequency table using rectangular areas proportional to the frequencies.

  • Inverse variation

    See Power function.

  • Linear regression

    A procedure for finding the straight line that is the best fit for the data

  • Negative angle

    Angle generated by clockwise rotation.

  • Nonsingular matrix

    A square matrix with nonzero determinant

  • Polynomial in x

    An expression that can be written in the form an x n + an-1x n-1 + Á + a1x + a0, where n is a nonnegative integer, the coefficients are real numbers, and an ? 0. The degree of the polynomial is n, the leading coefficient is an, the leading term is anxn, and the constant term is a0. (The number 0 is the zero polynomial)

  • Quadric surface

    The graph in three dimensions of a seconddegree equation in three variables.

  • Real number

    Any number that can be written as a decimal.

  • Solution of an equation or inequality

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

  • Term of a polynomial (function)

    An expression of the form anxn in a polynomial (function).
