Key Calculus Terms and definitions covered in this textbook
  • Absolute value of a complex number

    The absolute value of the complex number z = a + b is given by ?a2+b2; also, the length of the segment from the origin to z in the complex plane.

  • Difference identity

    An identity involving a trigonometric function of u - v

  • Distributive property

    a(b + c) = ab + ac and related properties

  • Index of summation

    See Summation notation.

  • Initial value of a function

    ƒ 0.

  • Irreducible quadratic over the reals

    A quadratic polynomial with real coefficients that cannot be factored using real coefficients.

  • Lower bound of f

    Any number b for which b < ƒ(x) for all x in the domain of ƒ

  • Midpoint (in a coordinate plane)

    For the line segment with endpoints (a,b) and (c,d), (aa + c2 ,b + d2)

  • Negative numbers

    Real numbers shown to the left of the origin on a number line.

  • Outliers

    Data items more than 1.5 times the IQR below the first quartile or above the third quartile.

  • Partial fraction decomposition

    See Partial fractions.

  • PH

    The measure of acidity

  • Product of matrices A and B

    The matrix in which each entry is obtained by multiplying the entries of a row of A by the corresponding entries of a column of B and then adding

  • Quartile

    The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

  • Reciprocal of a real number

    See Multiplicative inverse of a real number.

  • Sample space

    Set of all possible outcomes of an experiment.

  • Square matrix

    A matrix whose number of rows equals the number of columns.

  • Subtraction

    a - b = a + (-b)
