Key Calculus Terms and definitions covered in this textbook
• Acute angle

An angle whose measure is between 0° and 90°

• Anchor

See Mathematical induction.

• Arctangent function

See Inverse tangent function.

• Course

See Bearing.

• Equally likely outcomes

Outcomes of an experiment that have the same probability of occurring.

• Infinite limit

A special case of a limit that does not exist.

• Initial side of an angle

See Angle.

• Intercepted arc

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

• Mode of a data set

The category or number that occurs most frequently in the set.

• One-to-one rule of exponents

x = y if and only if bx = by.

• Polar form of a complex number

See Trigonometric form of a complex number.

• Reduced row echelon form

A matrix in row echelon form with every column that has a leading 1 having 0’s in all other positions.

• Shrink of factor c

A transformation of a graph obtained by multiplying all the x-coordinates (horizontal shrink) by the constant 1/c or all of the y-coordinates (vertical shrink) by the constant c, 0 < c < 1.

• Sine

The function y = sin x.

• Solution of a system in two variables

An ordered pair of real numbers that satisfies all of the equations or inequalities in the system

• 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

• Tangent

The function y = tan x

• Trichotomy property

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

• Vector equation for a line in space

The line through P0(x 0, y0, z0) in the direction of the nonzero vector V = <a, b, c> has vector equation r = r0 + tv , where r = <x,y,z>.

• Vertical stretch or shrink

See Stretch, Shrink.
