Key Calculus Terms and definitions covered in this textbook
  • 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)

  • Coefficient of determination

    The number r2 or R2 that measures how well a regression curve fits the data

  • Combinatorics

    A branch of mathematics related to determining the number of elements of a set or the number of ways objects can be arranged or combined

  • Cone

    See Right circular cone.

  • Coordinate(s) of a point

    The number associated with a point on a number line, or the ordered pair associated with a point in the Cartesian coordinate plane, or the ordered triple associated with a point in the Cartesian three-dimensional space

  • Dependent variable

    Variable representing the range value of a function (usually y)

  • Differentiable at x = a

    ƒ'(a) exists

  • Directed line segment

    See Arrow.

  • Equilibrium price

    See Equilibrium point.

  • Expanded form of a series

    A series written explicitly as a sum of terms (not in summation notation).

  • Factor

    In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

  • Least-squares line

    See Linear regression line.

  • n factorial

    For any positive integer n, n factorial is n! = n.(n - 1) . (n - 2) .... .3.2.1; zero factorial is 0! = 1

  • nth root of unity

    A complex number v such that vn = 1

  • Orthogonal vectors

    Two vectors u and v with u x v = 0.

  • Product of a scalar and a vector

    The product of scalar k and vector u = 8u1, u29 1or u = 8u1, u2, u392 is k.u = 8ku1, ku291or k # u = 8ku1, ku2, ku392,

  • Product of complex numbers

    (a + bi)(c + di) = (ac - bd) + (ad + bc)i

  • Slope

    Ratio change in y/change in x

  • symmetric about the x-axis

    A graph in which (x, -y) is on the graph whenever (x, y) is; or a graph in which (r, -?) or (-r, ?, -?) is on the graph whenever (r, ?) is

  • xy-plane

    The points x, y, 0 in Cartesian space.
