Key Calculus Terms and definitions covered in this textbook

If u < v , then u + w < v + w

• 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.

• Arccosecant function

See Inverse cosecant function.

• Average velocity

The change in position divided by the change in time.

• Directed line segment

See Arrow.

• Factor

In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

• Focal axis

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

• Focal width of a parabola

The length of the chord through the focus and perpendicular to the axis.

• Geometric series

A series whose terms form a geometric sequence.

• Linear regression equation

Equation of a linear regression line

• Linear regression line

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

• Major axis
