Key Calculus Terms and definitions covered in this textbook
• Ambiguous case

The case in which two sides and a nonincluded angle can determine two different triangles

• Bounded

A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

• Derivative of ƒ at x a

ƒ'(a) = lim x:a ƒ(x) - ƒ(a) x - a provided the limit exists

• Descriptive statistics

The gathering and processing of numerical information

• Equivalent arrows

Arrows that have the same magnitude and direction.

• First octant

The points (x, y, z) in space with x > 0 y > 0, and z > 0.

• Inductive step

See Mathematical induction.

• Inverse variation

See Power function.

• Invertible linear system

A system of n linear equations in n variables whose coefficient matrix has a nonzero determinant.

• Lemniscate

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

• Main diagonal

The diagonal from the top left to the bottom right of a square matrix

• Midpoint (in a coordinate plane)

For the line segment with endpoints (a,b) and (c,d), (aa + c2 ,b + d2)

• Nonsingular matrix

A square matrix with nonzero determinant

• Ordinary annuity

An annuity in which deposits are made at the same time interest is posted.

• Placebo

In an experimental study, an inactive treatment that is equivalent to the active treatment in every respect except for the factor about which an inference is to be made. Subjects in a blind experiment do not know if they have been given the active treatment or the placebo.

• Pole

See Polar coordinate system.

The distance from a point on a circle (or a sphere) to the center of the circle (or the sphere).

• Standard unit vectors

In the plane i = <1, 0> and j = <0,1>; in space i = <1,0,0>, j = <0,1,0> k = <0,0,1>

• Trichotomy property

For real numbers a and b, exactly one of the following is true: a < b, a = b , or a > b.

• Vertex of a cone

See Right circular cone.
