Key Calculus Terms and definitions covered in this textbook
• Cardioid

A limaçon whose polar equation is r = a ± a sin ?, or r = a ± a cos ?, where a > 0.

• Compounded k times per year

Interest compounded using the formula A = Pa1 + rkbkt where k = 1 is compounded annually, k = 4 is compounded quarterly k = 12 is compounded monthly, etc.

• Distributive property

a(b + c) = ab + ac and related properties

• Intercept

Point where a curve crosses the x-, y-, or z-axis in a graph.

• Lemniscate

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

• Line of symmetry

A line over which a graph is the mirror image of itself

• Linear regression line

The line for which the sum of the squares of the residuals is the smallest possible

• Local extremum

A local maximum or a local minimum

• Logistic growth function

A model of population growth: ƒ1x2 = c 1 + a # bx or ƒ1x2 = c1 + ae-kx, where a, b, c, and k are positive with b < 1. c is the limit to growth

• Measure of an angle

The number of degrees or radians in an angle

• Midpoint (on a number line)

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

• Obtuse triangle

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

• Parametric equations

Equations of the form x = ƒ(t) and y = g(t) for all t in an interval I. The variable t is the parameter and I is the parameter interval.

• Pascal’s triangle

A number pattern in which row n (beginning with n = 02) consists of the coefficients of the expanded form of (a+b)n.

• Rational function

Function of the form ƒ(x)/g(x) where ƒ(x) and g(x) are polynomials and g(x) is not the zero polynomial.

• Slope-intercept form (of a line)

y = mx + b

• Solution of a system in two variables

An ordered pair of real numbers that satisfies all of the equations or inequalities in the system

• Solve by substitution

Method for solving systems of linear equations.

• Spiral of Archimedes

The graph of the polar curve.

• Terms of a sequence

The range elements of a sequence.
