Key Calculus Terms and definitions covered in this textbook
• Arrow

The notation PQ denoting the directed line segment with initial point P and terminal point Q.

• Bounded above

A function is bounded above if there is a number B such that ƒ(x) ? B for all x in the domain of ƒ.

• Complex number

An expression a + bi, where a (the real part) and b (the imaginary part) are real numbers

• Cosecant

The function y = csc x

• Direct variation

See Power function.

• Distance (in a coordinate plane)

The distance d(P, Q) between P(x, y) and Q(x, y) d(P, Q) = 2(x 1 - x 2)2 + (y1 - y2)2

• Distributive property

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

• equation of a parabola

(x - h)2 = 4p(y - k) or (y - k)2 = 4p(x - h)

• Focal axis

The line through the focus and perpendicular to the directrix of a conic.

• Fundamental

Theorem of Algebra A polynomial function of degree has n complex zeros (counting multiplicity).

• Horizontal component

See Component form of a vector.

• Numerical model

A model determined by analyzing numbers or data in order to gain insight into a phenomenon, p. 64.

• Permutations of n objects taken r at a time

There are nPr = n!1n - r2! such permutations

• Pole

See Polar coordinate system.

• Re-expression of data

A transformation of a data set.

• Resolving a vector

Finding the horizontal and vertical components of a vector.

• Rose curve

A graph of a polar equation or r = a cos nu.

• Standard form of a polar equation of a conic

r = ke 1 e cos ? or r = ke 1 e sin ? ,

• Subtraction

a - b = a + (-b)

• Zero vector

The vector <0,0> or <0,0,0>.
