Key Calculus Terms and definitions covered in this textbook
  • Additive identity for the complex numbers

    0 + 0i is the complex number zero

  • Angle

    Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

  • Argument of a complex number

    The argument of a + bi is the direction angle of the vector {a,b}.

  • Compounded continuously

    Interest compounded using the formula A = Pert

  • Degree of a polynomial (function)

    The largest exponent on the variable in any of the terms of the polynomial (function)

  • Direction of an arrow

    The angle the arrow makes with the positive x-axis

  • Exponential decay function

    Decay modeled by ƒ(x) = a ? bx, a > 0 with 0 < b < 1.

  • Gaussian curve

    See Normal curve.

  • Graphical model

    A visible representation of a numerical or algebraic model.

  • nth power of a

    The number with n factors of a , where n is the exponent and a is the base.

  • Ordered pair

    A pair of real numbers (x, y), p. 12.

  • 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

  • Positive numbers

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

  • Proportional

    See Power function

  • Rectangular coordinate system

    See Cartesian coordinate system.

  • Secant line of ƒ

    A line joining two points of the graph of ƒ.

  • Variance

    The square of the standard deviation.

  • Vertex of an angle

    See Angle.

  • Work

    The product of a force applied to an object over a given distance W = ƒFƒ ƒAB!ƒ.

  • Yscl

    The scale of the tick marks on the y-axis in a viewing window.
