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

A triangle in which all angles measure less than 90°

• Binomial theorem

A theorem that gives an expansion formula for (a + b)n

• Decreasing on an interval

A function f is decreasing on an interval I if, for any two points in I, a positive change in x results in a negative change in ƒ(x)

• Directed distance

See Polar coordinates.

• Equation

A statement of equality between two expressions.

• Equilibrium point

A point where the supply curve and demand curve intersect. The corresponding price is the equilibrium price.

• Identity matrix

A square matrix with 1’s in the main diagonal and 0’s elsewhere, p. 534.

• Logistic growth function

A model of population growth: ƒ1x2 = c 1 + a # bx or ƒ1x2 = c1 + ae-kx, where a, b, c, and k are positive with b < 1. c is the limit to growth

• Maximum r-value

The value of |r| at the point on the graph of a polar equation that has the maximum distance from the pole

• Order of an m x n matrix

The order of an m x n matrix is m x n.

• Perpendicular lines

Two lines that are at right angles to each other

• Power-reducing identity

A trigonometric identity that reduces the power to which the trigonometric functions are raised.

• Residual

The difference y1 - (ax 1 + b), where (x1, y1)is a point in a scatter plot and y = ax + b is a line that fits the set of data.

• Resolving a vector

Finding the horizontal and vertical components of a vector.

• Response variable

A variable that is affected by an explanatory variable.

• Solve by substitution

Method for solving systems of linear equations.

• Standard unit vectors

In the plane i = <1, 0> and j = <0,1>; in space i = <1,0,0>, j = <0,1,0> k = <0,0,1>

• Sum of a finite arithmetic series

Sn = na a1 + a2 2 b = n 2 32a1 + 1n - 12d4,

• Sum of functions

(ƒ + g)(x) = ƒ(x) + g(x)

• Vertical translation

A shift of a graph up or down.
