Key Calculus Terms and definitions covered in this textbook

If u = v and w = z , then u + w = v + z

• Anchor

See Mathematical induction.

• Compounded monthly

See Compounded k times per year.

• Conversion factor

A ratio equal to 1, used for unit conversion

• End behavior asymptote of a rational function

A polynomial that the function approaches as.

• Factor

In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

• Geometric series

A series whose terms form a geometric sequence.

• Graphical model

A visible representation of a numerical or algebraic model.

• Leaf

The final digit of a number in a stemplot.

• Obtuse triangle

A triangle in which one angle is greater than 90°.

• Parametric equations for a line in space

The line through P0(x 0, y0, z 0) in the direction of the nonzero vector v = <a, b, c> has parametric equations x = x 0 + at, y = y 0 + bt, z = z0 + ct.

• Perpendicular lines

Two lines that are at right angles to each other

• Positive association

A relationship between two variables in which higher values of one variable are generally associated with higher values of the other variable, p. 717.

• Re-expression of data

A transformation of a data set.

• Response variable

A variable that is affected by an explanatory variable.

• Semiminor axis

The distance from the center of an ellipse to a point on the ellipse along a line perpendicular to the major axis.

• Sinusoid

A function that can be written in the form f(x) = a sin (b (x - h)) + k or f(x) = a cos (b(x - h)) + k. The number a is the amplitude, and the number h is the phase shift.

• Venn diagram

A visualization of the relationships among events within a sample space.

• Zero of a function

A value in the domain of a function that makes the function value zero.

• Zoom out

A procedure of a graphing utility used to view more of the coordinate plane (used, for example, to find theend behavior of a function).
