Key Calculus Terms and definitions covered in this textbook
  • Combination

    An arrangement of elements of a set, in which order is not important

  • Compounded annually

    See Compounded k times per year.

  • 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

  • Divergence

    A sequence or series diverges if it does not converge

  • Expanded form of a series

    A series written explicitly as a sum of terms (not in summation notation).

  • Invertible linear system

    A system of n linear equations in n variables whose coefficient matrix has a nonzero determinant.

  • 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 property of inequality

    If u < v and c > 0, then uc < vc. If u < and c < 0, then uc > vc

  • Nonsingular matrix

    A square matrix with nonzero determinant

  • Observational study

    A process for gathering data from a subset of a population through current or past observations. This differs from an experiment in that no treatment is imposed.

  • Parallelogram representation of vector addition

    Geometric representation of vector addition using the parallelogram determined by the position vectors.

  • Period

    See Periodic function.

  • Phase shift

    See Sinusoid.

  • Present value of an annuity T

    he net amount of your money put into an annuity.

  • Proportional

    See Power function

  • Reciprocal identity

    An identity that equates a trigonometric function with the reciprocal of another trigonometricfunction.

  • Slope-intercept form (of a line)

    y = mx + b

  • Solution of an equation or inequality

    A value of the variable (or values of the variables) for which the equation or inequality is true

  • Standard unit vectors

    In the plane i = <1, 0> and j = <0,1>; in space i = <1,0,0>, j = <0,1,0> k = <0,0,1>

  • z-coordinate

    The directed distance from the xy-plane to a point in space, or the third number in an ordered triple.
