Key Calculus Terms and definitions covered in this textbook
  • Direct variation

    See Power function.

  • Ellipse

    The set of all points in the plane such that the sum of the distances from a pair of fixed points (the foci) is a constant

  • Fundamental

    Theorem of Algebra A polynomial function of degree has n complex zeros (counting multiplicity).

  • Independent variable

    Variable representing the domain value of a function (usually x).

  • Inverse composition rule

    The composition of a one-toone function with its inverse results in the identity function.

  • Law of cosines

    a2 = b2 + c2 - 2bc cos A, b2 = a2 + c2 - 2ac cos B, c2 = a2 + b2 - 2ab cos C

  • Lemniscate

    A graph of a polar equation of the form r2 = a2 sin 2u or r 2 = a2 cos 2u.

  • Mapping

    A function viewed as a mapping of the elements of the domain onto the elements of the range

  • n factorial

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

  • Parallelogram representation of vector addition

    Geometric representation of vector addition using the parallelogram determined by the position vectors.

  • Product of functions

    (ƒg)(x) = ƒ(x)g(x)

  • Quadric surface

    The graph in three dimensions of a seconddegree equation in three variables.

  • Quotient polynomial

    See Division algorithm for polynomials.

  • Radian

    The measure of a central angle whose intercepted arc has a length equal to the circle’s radius.

  • Random behavior

    Behavior that is determined only by the laws of probability.

  • Reciprocal identity

    An identity that equates a trigonometric function with the reciprocal of another trigonometricfunction.

  • Resolving a vector

    Finding the horizontal and vertical components of a vector.

  • Solve by elimination or substitution

    Methods for solving systems of linear equations.

  • Sum of complex numbers

    (a + bi) + (c + di) = (a + c) + (b + d)i

  • Symmetric about the y-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
