Key Calculus Terms and definitions covered in this textbook
  • Arithmetic sequence

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

  • Binomial coefficients

    The numbers in Pascal’s triangle: nCr = anrb = n!r!1n - r2!

  • Boxplot (or box-and-whisker plot)

    A graph that displays a five-number summary

  • Common ratio

    See Geometric sequence.

  • Convenience sample

    A sample that sacrifices randomness for convenience

  • DMS measure

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

  • Equivalent arrows

    Arrows that have the same magnitude and direction.

  • Frequency distribution

    See Frequency table.

  • Invertible linear system

    A system of n linear equations in n variables whose coefficient matrix has a nonzero determinant.

  • Limit at infinity

    limx: qƒ1x2 = L means that ƒ1x2 gets arbitrarily close to L as x gets arbitrarily large; lim x:- q ƒ1x2 means that gets arbitrarily close to L as gets arbitrarily large

  • Numerical model

    A model determined by analyzing numbers or data in order to gain insight into a phenomenon, p. 64.

  • Quadratic equation in x

    An equation that can be written in the form ax 2 + bx + c = 01a ? 02

  • Richter scale

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

  • Secant

    The function y = sec x.

  • Semimajor axis

    The distance from the center to a vertex of an ellipse.

  • Standard form of a polynomial function

    ƒ(x) = an x n + an-1x n-1 + Á + a1x + a0

  • Standard form: equation of a circle

    (x - h)2 + (y - k2) = r 2

  • Sum of a finite arithmetic series

    Sn = na a1 + a2 2 b = n 2 32a1 + 1n - 12d4,

  • Unit vector

    Vector of length 1.

  • Venn diagram

    A visualization of the relationships among events within a sample space.
