Key Calculus Terms and definitions covered in this textbook
• Argument of a complex number

The argument of a + bi is the direction angle of the vector {a,b}.

• Constant function (on an interval)

ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

• 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)

• Demand curve

p = g(x), where x represents demand and p represents price

• equation of a quadratic function

ƒ(x) = ax 2 + bx + c(a ? 0)

• Finite sequence

A function whose domain is the first n positive integers for some fixed integer n.

• Grapher or graphing utility

Graphing calculator or a computer with graphing software.

• Initial point

See Arrow.

• Invertible linear system

A system of n linear equations in n variables whose coefficient matrix has a nonzero determinant.

• Parametric equations for a line in space

The line through P0(x 0, y0, z 0) in the direction of the nonzero vector v = <a, b, c> has parametric equations x = x 0 + at, y = y 0 + bt, z = z0 + ct.

• Pie chart

See Circle graph.

• Product of complex numbers

(a + bi)(c + di) = (ac - bd) + (ad + bc)i

• Random variable

A function that assigns real-number values to the outcomes in a sample space.

• Reflection across the y-axis

x, y and (-x,y) are reflections of each other across the y-axis.

• Resistant measure

A statistical measure that does not change much in response to outliers.

• Secant line of ƒ

A line joining two points of the graph of ƒ.

• Sum identity

An identity involving a trigonometric function of u + v

• Tree diagram

A visualization of the Multiplication Principle of Probability.

• Vector

An ordered pair <a, b> of real numbers in the plane, or an ordered triple <a, b, c> of real numbers in space. A vector has both magnitude and direction.

• y-intercept

A point that lies on both the graph and the y-axis.
