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.

  • Angle between vectors

    The angle formed by two nonzero vectors sharing a common initial point

  • Arccosecant function

    See Inverse cosecant function.

  • Blocking

    A feature of some experimental designs that controls for potential differences between subject groups by applying treatments randomly within homogeneous blocks of subjects

  • Categorical variable

    In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

  • Complex fraction

    See Compound fraction.

  • Derivative of ƒ

    The function defined by ƒ'(x) = limh:0ƒ(x + h) - ƒ(x)h for all of x where the limit exists

  • Empty set

    A set with no elements

  • Factor

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

  • Factoring (a polynomial)

    Writing a polynomial as a product of two or more polynomial factors.

  • Gaussian curve

    See Normal curve.

  • Identity

    An equation that is always true throughout its domain.

  • Linear regression

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

  • Main diagonal

    The diagonal from the top left to the bottom right of a square matrix

  • Parallelogram representation of vector addition

    Geometric representation of vector addition using the parallelogram determined by the position vectors.

  • Point-slope form (of a line)

    y - y1 = m1x - x 12.

  • Polynomial function

    A function in which ƒ(x)is a polynomial in x, p. 158.

  • Symmetric property of equality

    If a = b, then b = a

  • Third quartile

    See Quartile.

  • Vertex form for a quadratic function

    ƒ(x) = a(x - h)2 + k
