Key Calculus Terms and definitions covered in this textbook
  • Characteristic polynomial of a square matrix A

    det(xIn - A), where A is an n x n matrix

  • Feasible points

    Points that satisfy the constraints in a linear programming problem.

  • Gaussian curve

    See Normal curve.

  • Graph of a function ƒ

    The set of all points in the coordinate plane corresponding to the pairs (x, ƒ(x)) for x in the domain of ƒ.

  • Higher-degree polynomial function

    A polynomial function whose degree is ? 3

  • Logarithmic form

    An equation written with logarithms instead of exponents

  • Lower bound for real zeros

    A number c is a lower bound for the set of real zeros of ƒ if ƒ(x) Z 0 whenever x < c

  • n-set

    A set of n objects.

  • Number line graph of a linear inequality

    The graph of the solutions of a linear inequality (in x) on a number line

  • One-to-one rule of exponents

    x = y if and only if bx = by.

  • Origin

    The number zero on a number line, or the point where the x- and y-axes cross in the Cartesian coordinate system, or the point where the x-, y-, and z-axes cross in Cartesian three-dimensional space

  • Phase shift

    See Sinusoid.

  • Probability of an event in a finite sample space of equally likely outcomes

    The number of outcomes in the event divided by the number of outcomes in the sample space.

  • Quadrant

    Any one of the four parts into which a plane is divided by the perpendicular coordinate axes.

  • Removable discontinuity at x = a

    lim x:a- ƒ(x) = limx:a+ ƒ(x) but either the common limit is not equal ƒ(a) to ƒ(a) or is not defined

  • Riemann sum

    A sum where the interval is divided into n subintervals of equal length and is in the ith subinterval.

  • Semimajor axis

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

  • Stem

    The initial digit or digits of a number in a stemplot.

  • Tangent

    The function y = tan x

  • Transitive property

    If a = b and b = c , then a = c. Similar properties hold for the inequality symbols <, >, ?, ?.
