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.

  • Addition property of equality

    If u = v and w = z , then u + w = v + z

  • Anchor

    See Mathematical induction.

  • Angle of depression

    The acute angle formed by the line of sight (downward) and the horizontal

  • Arrow

    The notation PQ denoting the directed line segment with initial point P and terminal point Q.

  • Bar chart

    A rectangular graphical display of categorical data.

  • Bias

    A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

  • Double inequality

    A statement that describes a bounded interval, such as 3 ? x < 5

  • Factoring (a polynomial)

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

  • Graph of an inequality in x and y

    The set of all points in the coordinate plane corresponding to the solutions x, y of the inequality.

  • Identity matrix

    A square matrix with 1’s in the main diagonal and 0’s elsewhere, p. 534.

  • Inverse of a matrix

    The inverse of a square matrix A, if it exists, is a matrix B, such that AB = BA = I , where I is an identity matrix.

  • Midpoint (in Cartesian space)

    For the line segment with endpoints (x 1, y1, z 1) and (x2, y2, z2), ax 1 + x 22 ,y1 + y22 ,z 1 + z 22 b

  • Mode of a data set

    The category or number that occurs most frequently in the set.

  • Reflection across the y-axis

    x, y and (-x,y) are reflections of each other across the y-axis.

  • Synthetic division

    A procedure used to divide a polynomial by a linear factor, x - a

  • Term of a polynomial (function)

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

  • Upper bound for ƒ

    Any number B for which ƒ(x) ? B for all x in the domain of ƒ.

  • Vertex of an angle

    See Angle.

  • Ymax

    The y-value of the top of the viewing window.
