Key Calculus Terms and definitions covered in this textbook
• Angle between vectors

The angle formed by two nonzero vectors sharing a common initial point

• Annual percentage rate (APR)

The annual interest rate

• Aphelion

The farthest point from the Sun in a planet’s orbit

• Constant of variation

See Power function.

• Cotangent

The function y = cot x

• Dependent variable

Variable representing the range value of a function (usually y)

• Derivative of ƒ at x a

ƒ'(a) = lim x:a ƒ(x) - ƒ(a) x - a provided the limit exists

• Differentiable at x = a

ƒ'(a) exists

• Direct variation

See Power function.

• Directrix of a parabola, ellipse, or hyperbola

A line used to determine the conic

• Graph of parametric equations

The set of all points in the coordinate plane corresponding to the ordered pairs determined by the parametric equations.

• Linear correlation

A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

• Linear inequality in x

An inequality that can be written in the form ax + b < 0 ,ax + b … 0 , ax + b > 0, or ax + b Ú 0, where a and b are real numbers and a Z 0

• Octants

The eight regions of space determined by the coordinate planes.

• Projectile motion

The movement of an object that is subject only to the force of gravity

• Remainder polynomial

See Division algorithm for polynomials.

• Standard position (angle)

An angle positioned on a rectangular coordinate system with its vertex at the origin and its initial side on the positive x-axis

• 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 line test

A test for determining whether a graph is a function.

• Zero matrix

A matrix consisting entirely of zeros.
