Key Calculus Terms and definitions covered in this textbook
  • Absolute maximum

    A value ƒ(c) is an absolute maximum value of ƒ if ƒ(c) ? ƒ(x) for all x in the domain of ƒ.

  • Base

    See Exponential function, Logarithmic function, nth power of a.

  • Cofunction identity

    An identity that relates the sine, secant, or tangent to the cosine, cosecant, or cotangent, respectively

  • Conjugate axis of a hyperbola

    The line segment of length 2b that is perpendicular to the focal axis and has the center of the hyperbola as its midpoint

  • Elimination method

    A method of solving a system of linear equations

  • Explanatory variable

    A variable that affects a response variable.

  • Exponential decay function

    Decay modeled by ƒ(x) = a ? bx, a > 0 with 0 < b < 1.

  • Factor

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

  • Integers

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

  • Magnitude of an arrow

    The magnitude of PQ is the distance between P and Q

  • Natural logarithm

    A logarithm with base e.

  • Order of magnitude (of n)

    log n.

  • Polynomial in x

    An expression that can be written in the form an x n + an-1x n-1 + Á + a1x + a0, where n is a nonnegative integer, the coefficients are real numbers, and an ? 0. The degree of the polynomial is n, the leading coefficient is an, the leading term is anxn, and the constant term is a0. (The number 0 is the zero polynomial)

  • Quotient of complex numbers

    a + bi c + di = ac + bd c2 + d2 + bc - ad c2 + d2 i

  • Removable discontinuity at x = a

    lim x:a- ƒ(x) = limx:a+ ƒ(x) but either the common limit is not equal ƒ(a) to ƒ(a) or is not defined

  • Resolving a vector

    Finding the horizontal and vertical components of a vector.

  • RRAM

    A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the right-hand end point of each subinterval.

  • Statistic

    A number that measures a quantitative variable for a sample from a population.

  • Sum of functions

    (ƒ + g)(x) = ƒ(x) + g(x)

  • Term of a polynomial (function)

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