Key Calculus Terms and definitions covered in this textbook
  • Acceleration due to gravity

    g ? 32 ft/sec2 ? 9.8 m/sec

  • Angle between vectors

    The angle formed by two nonzero vectors sharing a common initial point

  • Blind experiment

    An experiment in which subjects do not know if they have been given an active treatment or a placebo

  • Commutative properties

    a + b = b + a ab = ba

  • 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

  • Focal length of a parabola

    The directed distance from the vertex to the focus.

  • Inferential statistics

    Using the science of statistics to make inferences about the parameters in a population from a sample.

  • Line graph

    A graph of data in which consecutive data points are connected by line segments

  • Logarithmic re-expression of data

    Transformation of a data set involving the natural logarithm: exponential regression, natural logarithmic regression, power regression

  • LRAM

    A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the left-hand endpoint of each subinterval

  • Measure of center

    A measure of the typical, middle, or average value for a data set

  • Midpoint (on a number line)

    For the line segment with endpoints a and b, a + b2

  • Multiplicity

    The multiplicity of a zero c of a polynomial ƒ(x) of degree n > 0 is the number of times the factor (x - c) (x - z 2) Á (x - z n)

  • Partial fraction decomposition

    See Partial fractions.

  • Polar distance formula

    The distance between the points with polar coordinates (r1, ?1 ) and (r2, ?2 ) = 2r 12 + r 22 - 2r1r2 cos 1?1 - ?22

  • Pole

    See Polar coordinate system.

  • Product rule of logarithms

    ogb 1RS2 = logb R + logb S, R > 0, S > 0,

  • Replication

    The principle of experimental design that minimizes the effects of chance variation by repeating the experiment multiple times.

  • Root of a number

    See Principal nth root.

  • Sample survey

    A process for gathering data from a subset of a population, usually through direct questioning.
