Key Calculus Terms and definitions covered in this textbook
  • Angle between vectors

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

  • Arc length formula

    The length of an arc in a circle of radius r intercepted by a central angle of u radians is s = r u.

  • Components of a vector

    See Component form of a vector.

  • Compounded annually

    See Compounded k times per year.

  • Dependent event

    An event whose probability depends on another event already occurring

  • Descriptive statistics

    The gathering and processing of numerical information

  • Difference of functions

    (ƒ - g)(x) = ƒ(x) - g(x)

  • 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.

  • Linear inequality in two variables x and y

    An inequality that can be written in one of the following forms: y 6 mx + b, y … mx + b, y 7 mx + b, or y Ú mx + b with m Z 0

  • Nappe

    See Right circular cone.

  • Negative angle

    Angle generated by clockwise rotation.

  • Number line graph of a linear inequality

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

  • 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)

  • Randomization

    The principle of experimental design that makes it possible to use the laws of probability when making inferences.

  • Rational expression

    An expression that can be written as a ratio of two polynomials.

  • Right circular cone

    The surface created when a line is rotated about a second line that intersects but is not perpendicular to the first line.

  • Subtraction

    a - b = a + (-b)

  • Tree diagram

    A visualization of the Multiplication Principle of Probability.

  • Unit vector in the direction of a vector

    A unit vector that has the same direction as the given vector.

  • xy-plane

    The points x, y, 0 in Cartesian space.
