Key Calculus Terms and definitions covered in this textbook
• Binomial coefficients

The numbers in Pascal’s triangle: nCr = anrb = n!r!1n - r2!

• Binomial probability

In an experiment with two possible outcomes, the probability of one outcome occurring k times in n independent trials is P1E2 = n!k!1n - k2!pk11 - p) n-k where p is the probability of the outcome occurring once

• Chord of a conic

A line segment with endpoints on the conic

• Completing the square

A method of adding a constant to an expression in order to form a perfect square

• Endpoint of an interval

A real number that represents one “end” of an interval.

• First octant

The points (x, y, z) in space with x > 0 y > 0, and z > 0.

• Identity

An equation that is always true throughout its domain.

• Inverse cotangent function

The function y = cot-1 x

• Inverse tangent function

The function y = tan-1 x

• Invertible linear system

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

• Irrational zeros

Zeros of a function that are irrational numbers.

• Line of symmetry

A line over which a graph is the mirror image of itself

• Multiplication principle of probability

If A and B are independent events, then P(A and B) = P(A) # P(B). If Adepends on B, then P(A and B) = P(A|B) # P(B)

• Nonsingular matrix

A square matrix with nonzero determinant

• Recursively defined sequence

A sequence defined by giving the first term (or the first few terms) along with a procedure for finding the subsequent terms.

• Sequence

See Finite sequence, Infinite sequence.

• Triangular form

A special form for a system of linear equations that facilitates finding the solution.

• Unbounded interval

An interval that extends to -? or ? (or both).

• Zero factor property

If ab = 0 , then either a = 0 or b = 0.
