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

    An angle whose measure is between 0° and 90°

  • Additive identity for the complex numbers

    0 + 0i is the complex number zero

  • Arccosecant function

    See Inverse cosecant function.

  • Bar chart

    A rectangular graphical display of categorical data.

  • Demand curve

    p = g(x), where x represents demand and p represents price

  • End behavior

    The behavior of a graph of a function as.

  • Equation

    A statement of equality between two expressions.

  • Focus, foci

    See Ellipse, Hyperbola, Parabola.

  • Inverse reflection principle

    If the graph of a relation is reflected across the line y = x , the graph of the inverse relation results.

  • Limit at infinity

    limx: qƒ1x2 = L means that ƒ1x2 gets arbitrarily close to L as x gets arbitrarily large; lim x:- q ƒ1x2 means that gets arbitrarily close to L as gets arbitrarily large

  • Multiplication principle of counting
