Key Calculus Terms and definitions covered in this textbook
• Algebraic model

An equation that relates variable quantities associated with phenomena being studied

• Bearing

Measure of the clockwise angle that the line of travel makes with due north

• Equal complex numbers

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

• Half-life

The amount of time required for half of a radioactive substance to decay.

• Heron’s formula

The area of ¢ABC with semiperimeter s is given by 2s1s - a21s - b21s - c2.

• Imaginary axis

See Complex plane.

• Intercepted arc

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

• Negative association

A relationship between two variables in which higher values of one variable are generally associated with lower values of the other variable.

• Odd function

A function whose graph is symmetric about the origin (ƒ(-x) = -ƒ(x) for all x in the domain of f).

• One-to-one rule of exponents

x = y if and only if bx = by.

• Parallel lines

Two lines that are both vertical or have equal slopes.

The graph in three dimensions of a seconddegree equation in three variables.

• Quotient of functions
