Key Calculus Terms and definitions covered in this textbook
  • Addition principle of probability.

    P(A or B) = P(A) + P(B) - P(A and B). If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B)

  • Augmented matrix

    A matrix that represents a system of equations.

  • Bounded

    A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

  • 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

  • Continuous function

    A function that is continuous on its entire domain

  • Inverse cosine function

    The function y = cos-1 x

  • Inverse of a matrix

    The inverse of a square matrix A, if it exists, is a matrix B, such that AB = BA = I , where I is an identity matrix.

  • Linear regression equation

    Equation of a linear regression line

  • Lower bound of f

    Any number b for which b < ƒ(x) for all x in the domain of ƒ

  • Opens upward or downward

    A parabola y = ax 2 + bx + c opens upward if a > 0 and opens downward if a < 0.

  • Position vector of the point (a, b)

    The vector <a,b>.

  • Product of complex numbers

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

  • Proportional

    See Power function

  • Random behavior

    Behavior that is determined only by the laws of probability.

  • Spiral of Archimedes

    The graph of the polar curve.

  • Stretch of factor c

    A transformation of a graph obtained by multiplying all the x-coordinates (horizontal stretch) by the constant 1/c, or all of the y-coordinates (vertical stretch) of the points by a constant c, c, > 1.

  • Sum of an infinite series

    See Convergence of a series

  • Symmetric difference quotient of ƒ at a

    ƒ(x + h) - ƒ(x - h) 2h

  • Third quartile

    See Quartile.

  • Tree diagram

    A visualization of the Multiplication Principle of Probability.
