Key Calculus Terms and definitions covered in this textbook
  • Census

    An observational study that gathers data from an entire population

  • Commutative properties

    a + b = b + a ab = ba

  • Compound fraction

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

  • 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

  • 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

  • Gaussian curve

    See Normal curve.

  • Gaussian elimination

    A method of solving a system of n linear equations in n unknowns.

  • Half-plane

    The graph of the linear inequality y ? ax + b, y > ax + b y ? ax + b, or y < ax + b.

  • Independent variable

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

  • Inverse of a matrix

    The inverse of a square matrix A, if it exists, is a matrix B, such that AB = BA = I , where I is an identity matrix.

  • Inverse reflection principle

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

  • NINT (ƒ(x), x, a, b)

    A calculator approximation to ?ab ƒ(x)dx

  • nth power of a

    The number with n factors of a , where n is the exponent and a is the base.

  • Parallelogram representation of vector addition

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

  • Polar coordinates

    The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

  • Probability of an event in a finite sample space of equally likely outcomes

    The number of outcomes in the event divided by the number of outcomes in the sample space.

  • Range (in statistics)

    The difference between the greatest and least values in a data set.

  • Recursively defined sequence

    A sequence defined by giving the first term (or the first few terms) along with a procedure for finding the subsequent terms.

  • Transformation

    A function that maps real numbers to real numbers.

  • Vertex of a cone

    See Right circular cone.
