Key Calculus Terms and definitions covered in this textbook
  • Addition property of inequality

    If u < v , then u + w < v + w

  • Algebraic model

    An equation that relates variable quantities associated with phenomena being studied

  • Augmented matrix

    A matrix that represents a system of equations.

  • Census

    An observational study that gathers data from an entire population

  • Complements or complementary angles

    Two angles of positive measure whose sum is 90°

  • End behavior

    The behavior of a graph of a function as.

  • equation of an ellipse

    (x - h2) a2 + (y - k)2 b2 = 1 or (y - k)2 a2 + (x - h)2 b2 = 1

  • Exponent

    See nth power of a.

  • Ordered pair

    A pair of real numbers (x, y), p. 12.

  • Phase shift

    See Sinusoid.

  • Product rule of logarithms

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

  • Pseudo-random numbers

    Computer-generated numbers that can be used to approximate true randomness in scientific studies. Since they depend on iterative computer algorithms, they are not truly random

  • Quartile

    The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

  • Quotient identities

    tan ?= sin ?cos ?and cot ?= cos ? sin ?

  • Range of a function

    The set of all output values corresponding to elements in the domain.

  • Residual

    The difference y1 - (ax 1 + b), where (x1, y1)is a point in a scatter plot and y = ax + b is a line that fits the set of data.

  • Sample survey

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

  • Solve a system

    To find all solutions of a system.

  • Statistic

    A number that measures a quantitative variable for a sample from a population.

  • Unit vector in the direction of a vector

    A unit vector that has the same direction as the given vector.
