Key Calculus Terms and definitions covered in this textbook
• Absolute maximum

A value ƒ(c) is an absolute maximum value of ƒ if ƒ(c) ? ƒ(x) for all x in the domain of ƒ.

• Additive inverse of a complex number

The opposite of a + bi, or -a - bi

• 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.

• Arctangent function

See Inverse tangent function.

• equation of a hyperbola

(x - h)2 a2 - (y - k)2 b2 = 1 or (y - k)2 a2 - (x - h)2 b2 = 1

• Factoring (a polynomial)

Writing a polynomial as a product of two or more polynomial factors.

• Imaginary axis

See Complex plane.

• Index

• Minute

Angle measure equal to 1/60 of a degree.

• Negative numbers

Real numbers shown to the left of the origin on a number line.

• Number line graph of a linear inequality

The graph of the solutions of a linear inequality (in x) on a number line

• Parallelogram representation of vector addition

Geometric representation of vector addition using the parallelogram determined by the position vectors.

• Polar coordinates

The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

A function in which ƒ(x)is a polynomial in x, p. 158.

• Product rule of logarithms

ogb 1RS2 = logb R + logb S, R > 0, S > 0,

• Reflection
