Key Calculus Terms and definitions covered in this textbook
  • Augmented matrix

    A matrix that represents a system of equations.

  • Circle graph

    A circular graphical display of categorical data

  • Coefficient of determination

    The number r2 or R2 that measures how well a regression curve fits the data

  • Common difference

    See Arithmetic sequence.

  • Complex fraction

    See Compound fraction.

  • Complex number

    An expression a + bi, where a (the real part) and b (the imaginary part) are real numbers

  • 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

  • Difference of complex numbers

    (a + bi) - (c + di) = (a - c) + (b - d)i

  • Elimination method

    A method of solving a system of linear equations

  • equation of a hyperbola

    (x - h)2 a2 - (y - k)2 b2 = 1 or (y - k)2 a2 - (x - h)2 b2 = 1

  • Inductive step

    See Mathematical induction.

  • Infinite discontinuity at x = a

    limx:a + x a ƒ(x) = q6 or limx:a - ƒ(x) = q.

  • Lemniscate

    A graph of a polar equation of the form r2 = a2 sin 2u or r 2 = a2 cos 2u.

  • Linear inequality in x

    An inequality that can be written in the form ax + b < 0 ,ax + b … 0 , ax + b > 0, or ax + b Ú 0, where a and b are real numbers and a Z 0

  • Numerical model

    A model determined by analyzing numbers or data in order to gain insight into a phenomenon, p. 64.

  • Reciprocal identity

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

  • Relevant domain

    The portion of the domain applicable to the situation being modeled.

  • Scalar

    A real number.

  • Variation

    See Power function.

  • Vector equation for a line in space

    The line through P0(x 0, y0, z0) in the direction of the nonzero vector V = <a, b, c> has vector equation r = r0 + tv , where r = <x,y,z>.
