Key Calculus Terms and definitions covered in this textbook
  • Anchor

    See Mathematical induction.

  • Blind experiment

    An experiment in which subjects do not know if they have been given an active treatment or a placebo

  • Definite integral

    The definite integral of the function ƒ over [a,b] is Lbaƒ(x) dx = limn: q ani=1 ƒ(xi) ¢x provided the limit of the Riemann sums exists

  • Determinant

    A number that is associated with a square matrix

  • Discriminant

    For the equation ax 2 + bx + c, the expression b2 - 4ac; for the equation Ax2 + Bxy + Cy2 + Dx + Ey + F = 0, the expression B2 - 4AC

  • Elements of a matrix

    See Matrix element.

  • Equation

    A statement of equality between two expressions.

  • Focus, foci

    See Ellipse, Hyperbola, Parabola.

  • Identity function

    The function ƒ(x) = x.

  • Independent variable

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

  • Limit

    limx:aƒ1x2 = L means that ƒ(x) gets arbitrarily close to L as x gets arbitrarily close (but not equal) to a

  • Linear equation in x

    An equation that can be written in the form ax + b = 0, where a and b are real numbers and a Z 0

  • Logarithmic re-expression of data

    Transformation of a data set involving the natural logarithm: exponential regression, natural logarithmic regression, power regression

  • LRAM

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

  • Open interval

    An interval that does not include its endpoints.

  • Opens upward or downward

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

  • Ordered set

    A set is ordered if it is possible to compare any two elements and say that one element is “less than” or “greater than” the other.

  • Positive numbers

    Real numbers shown to the right of the origin on a number line.

  • Slope

    Ratio change in y/change in x

  • Work

    The product of a force applied to an object over a given distance W = ƒFƒ ƒAB!ƒ.
