Key Calculus Terms and definitions covered in this textbook
  • Central angle

    An angle whose vertex is the center of a circle

  • Compounded monthly

    See Compounded k times per year.

  • Differentiable at x = a

    ƒ'(a) exists

  • Divergence

    A sequence or series diverges if it does not converge

  • Domain of validity of an identity

    The set of values of the variable for which both sides of the identity are defined

  • Equilibrium point

    A point where the supply curve and demand curve intersect. The corresponding price is the equilibrium price.

  • Factor

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

  • Five-number summary

    The minimum, first quartile, median, third quartile, and maximum of a data set.

  • Function

    A relation that associates each value in the domain with exactly one value in the range.

  • Horizontal Line Test

    A test for determining whether the inverse of a relation is a function.

  • Imaginary part of a complex number

    See Complex number.

  • Increasing on an interval

    A function ƒ is increasing on an interval I if, for any two points in I, a positive change in x results in a positive change in.

  • Jump discontinuity at x a

  • Periodic function

    A function ƒ for which there is a positive number c such that for every value t in the domain of ƒ. The smallest such number c is the period of the function.

  • 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)

  • Sum of a finite geometric series

    Sn = a111 - r n 2 1 - r

  • Symmetric about the origin

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

  • Term of a polynomial (function)

    An expression of the form anxn in a polynomial (function).

  • Vertical line test

    A test for determining whether a graph is a function.

  • Work
