Key Calculus Terms and definitions covered in this textbook
• Absolute minimum

A value ƒ(c) is an absolute minimum value of ƒ if ƒ(c) ? ƒ(x)for all x in the domain of ƒ.

• Angular speed

Speed of rotation, typically measured in radians or revolutions per unit time

• Boundary

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

• Census

An observational study that gathers data from an entire population

• Convergence of a series

A series aqk=1 ak converges to a sum S if imn: q ank=1ak = S

• Difference of complex numbers

(a + bi) - (c + di) = (a - c) + (b - d)i

• Dihedral angle

An angle formed by two intersecting planes,

• Directed line segment

See Arrow.

• Distance (in a coordinate plane)

The distance d(P, Q) between P(x, y) and Q(x, y) d(P, Q) = 2(x 1 - x 2)2 + (y1 - y2)2

• Even function

A function whose graph is symmetric about the y-axis for all x in the domain of ƒ.

• Identity function

The function ƒ(x) = x.

• Left-hand limit of f at x a

The limit of ƒ as x approaches a from the left.

• Multiplicative inverse of a matrix

See Inverse of a matrix

• Negative association

A relationship between two variables in which higher values of one variable are generally associated with lower values of the other variable.

• Negative linear correlation

See Linear correlation.

• Opens upward or downward

A parabola y = ax 2 + bx + c opens upward if a > 0 and opens downward if a < 0.

• Pythagorean

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

• Random numbers

Numbers that can be used by researchers to simulate randomness in scientific studies (they are usually obtained from lengthy tables of decimal digits that have been generated by verifiably random natural phenomena).

• Sample standard deviation

The standard deviation computed using only a sample of the entire population.

• Viewing window

The rectangular portion of the coordinate plane specified by the dimensions [Xmin, Xmax] by [Ymin, Ymax].
