Key Calculus Terms and definitions covered in this textbook
• Additive identity for the complex numbers

0 + 0i is the complex number zero

• Bias

A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

• 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.

• Coefficient

The real number multiplied by the variable(s) in a polynomial term

• Component form of a vector

If a vector’s representative in standard position has a terminal point (a,b) (or (a, b, c)) , then (a,b) (or (a, b, c)) is the component form of the vector, and a and b are the horizontal and vertical components of the vector (or a, b, and c are the x-, y-, and z-components of the vector, respectively)

• Cone

See Right circular cone.

• Control

The principle of experimental design that makes it possible to rule out other factors when making inferences about a particular explanatory variable

• Directed angle

See Polar coordinates.

• Ellipsoid of revolution

A surface generated by rotating an ellipse about its major axis

• Graph of an equation in x and y

The set of all points in the coordinate plane corresponding to the pairs x, y that are solutions of the equation.

• Horizontal shrink or stretch

See Shrink, stretch.

• Inductive step

See Mathematical induction.

• Intercepted arc

Arc of a circle between the initial side and terminal side of a central angle.

• Obtuse triangle

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

• Parametric curve

The graph of parametric equations.

• Point-slope form (of a line)

y - y1 = m1x - x 12.

• Sequence of partial sums

The sequence {Sn} , where Sn is the nth partial sum of the series, that is, the sum of the first n terms of the series.

• Summation notation

The series a nk=1ak, where n is a natural number ( or ?) is in summation notation and is read "the sum of ak from k = 1 to n(or infinity).” k is the index of summation, and ak is the kth term of the series

• Supply curve

p = ƒ(x), where x represents production and p represents price

• Trichotomy property

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