Key Calculus Terms and definitions covered in this textbook
  • Amplitude

    See Sinusoid.

  • Argument of a complex number

    The argument of a + bi is the direction angle of the vector {a,b}.

  • Descriptive statistics

    The gathering and processing of numerical information

  • Distance (on a number line)

    The distance between real numbers a and b, or |a - b|

  • Exponential form

    An equation written with exponents instead of logarithms.

  • Future value of an annuity

    The net amount of money returned from an annuity.

  • Gaussian elimination

    A method of solving a system of n linear equations in n unknowns.

  • Graph of parametric equations

    The set of all points in the coordinate plane corresponding to the ordered pairs determined by the parametric equations.

  • Heron’s formula

    The area of ¢ABC with semiperimeter s is given by 2s1s - a21s - b21s - c2.

  • Integers

    The numbers . . ., -3, -2, -1, 0,1,2,...2

  • Inverse composition rule

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

  • Inverse relation (of the relation R)

    A relation that consists of all ordered pairs b, a for which a, b belongs to R.

  • nth root of unity

    A complex number v such that vn = 1

  • One-to-one rule of logarithms

    x = y if and only if logb x = logb y.

  • Pie chart

    See Circle graph.

  • Power-reducing identity

    A trigonometric identity that reduces the power to which the trigonometric functions are raised.

  • Quotient polynomial

    See Division algorithm for polynomials.

  • Reciprocal of a real number

    See Multiplicative inverse of a real number.

  • Reference triangle

    For an angle ? in standard position, a reference triangle is a triangle formed by the terminal side of angle ?, the x-axis, and a perpendicular dropped from a point on the terminal side to the x-axis. The angle in a reference triangle at the origin is the reference angle

  • Square matrix

    A matrix whose number of rows equals the number of columns.
