Key Calculus Terms and definitions covered in this textbook
• Arc length formula

The length of an arc in a circle of radius r intercepted by a central angle of u radians is s = r u.

• 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.

• Cotangent

The function y = cot x

• Directrix of a parabola, ellipse, or hyperbola

A line used to determine the conic

• Equal complex numbers

Complex numbers whose real parts are equal and whose imaginary parts are equal.

• Exponent

See nth power of a.

• Horizontal asymptote

The line is a horizontal asymptote of the graph of a function ƒ if lim x:- q ƒ(x) = or lim x: q ƒ(x) = b

• Implicitly defined function

A function that is a subset of a relation defined by an equation in x and y.

• Inequality symbol or

<,>,<,>.

• Inverse tangent function

The function y = tan-1 x

• Limit at infinity

limx: qƒ1x2 = L means that ƒ1x2 gets arbitrarily close to L as x gets arbitrarily large; lim x:- q ƒ1x2 means that gets arbitrarily close to L as gets arbitrarily large

• Line of symmetry

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

• 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

• Outcomes

The various possible results of an experiment.

• RRAM

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

• Secant line of ƒ

A line joining two points of the graph of ƒ.

• Time plot

A line graph in which time is measured on the horizontal axis.

• Trigonometric form of a complex number

r(cos ? + i sin ?)

• z-coordinate

The directed distance from the xy-plane to a point in space, or the third number in an ordered triple.

• Zero factorial

See n factorial.
