Key Calculus Terms and definitions covered in this textbook
  • Angle of depression

    The acute angle formed by the line of sight (downward) and the horizontal

  • Arccotangent function

    See Inverse cotangent function.

  • Axis of symmetry

    See Line of symmetry.

  • Basic logistic function

    The function ƒ(x) = 1 / 1 + e-x

  • Binomial coefficients

    The numbers in Pascal’s triangle: nCr = anrb = n!r!1n - r2!

  • Characteristic polynomial of a square matrix A

    det(xIn - A), where A is an n x n matrix

  • Compound fraction

    A fractional expression in which the numerator or denominator may contain fractions

  • Elementary row operations

    The following three row operations: Multiply all elements of a row by a nonzero constant; interchange two rows; and add a multiple of one row to another row

  • Graphical model

    A visible representation of a numerical or algebraic model.

  • Irrational zeros

    Zeros of a function that are irrational numbers.

  • Leibniz notation

    The notation dy/dx for the derivative of ƒ.
