Key Calculus Terms and definitions covered in this textbook
  • Complex plane

    A coordinate plane used to represent the complex numbers. The x-axis of the complex plane is called the real axis and the y-axis is the imaginary axis

  • Compound interest

    Interest that becomes part of the investment

  • Conjugate axis of a hyperbola

    The line segment of length 2b that is perpendicular to the focal axis and has the center of the hyperbola as its midpoint

  • Cube root

    nth root, where n = 3 (see Principal nth root),

  • Horizontal translation

    A shift of a graph to the left or right.

  • Least-squares line

    See Linear regression line.

  • Linear equation in x

    An equation that can be written in the form ax + b = 0, where a and b are real numbers and a Z 0

  • Multiplicative inverse of a matrix

    See Inverse of a matrix

  • Piecewise-defined function

    A function whose domain is divided into several parts with a different function rule applied to each part, p. 104.

  • Polar coordinate system

    A coordinate system whose ordered pair is based on the directed distance from a central point (the pole) and the angle measured from a ray from the pole (the polar axis)

  • Polynomial in x

    An expression that can be written in the form an x n + an-1x n-1 + Á + a1x + a0, where n is a nonnegative integer, the coefficients are real numbers, and an ? 0. The degree of the polynomial is n, the leading coefficient is an, the leading term is anxn, and the constant term is a0. (The number 0 is the zero polynomial)

  • Positive numbers

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

  • Power regression

    A procedure for fitting a curve y = a . x b to a set of data.

  • Real part of a complex number

    See Complex number.

  • Scientific notation

    A positive number written as c x 10m, where 1 ? c < 10 and m is an integer.

  • Sinusoidal regression

    A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

  • Slant line

    A line that is neither horizontal nor vertical

  • Solution set of an inequality

    The set of all solutions of an inequality

  • Xmax

    The x-value of the right side of the viewing window,.

  • yz-plane

    The points (0, y, z) in Cartesian space.
