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

An angle whose measure is between 0° and 90°

• Arrow

The notation PQ denoting the directed line segment with initial point P and terminal point Q.

• Boundary

The set of points on the “edge” of a region

• Bounded below

A function is bounded below if there is a number b such that b ? ƒ(x) for all x in the domain of f.

• Complex conjugates

Complex numbers a + bi and a - bi

• Control

The principle of experimental design that makes it possible to rule out other factors when making inferences about a particular explanatory variable

• Equation

A statement of equality between two expressions.

• Exponent

See nth power of a.

• Exponential form

An equation written with exponents instead of logarithms.

• Limit to growth

See Logistic growth function.

• Logarithmic form

An equation written with logarithms instead of exponents

• Permutation

An arrangement of elements of a set, in which order is important.

• Position vector of the point (a, b)

The vector <a,b>.

• Pythagorean

Theorem In a right triangle with sides a and b and hypotenuse c, c2 = a2 + b2

• Semimajor axis

The distance from the center to a vertex of an ellipse.

• Slope

Ratio change in y/change in x

• Solve algebraically

Use an algebraic method, including paper and pencil manipulation and obvious mental work, with no calculator or grapher use. When appropriate, the final exact solution may be approximated by a calculator

• 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>

• Transverse axis

The line segment whose endpoints are the vertices of a hyperbola.
