Key Calculus Terms and definitions covered in this textbook

If u < v , then u + w < v + w

• Angle between vectors

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

• Cofunction identity

An identity that relates the sine, secant, or tangent to the cosine, cosecant, or cotangent, respectively

• Determinant

A number that is associated with a square matrix

• Double-blind experiment

A blind experiment in which the researcher gathering data from the subjects is not told which subjects have received which treatment

• equation of an ellipse

(x - h2) a2 + (y - k)2 b2 = 1 or (y - k)2 a2 + (x - h)2 b2 = 1

• Equivalent vectors

Vectors with the same magnitude and direction.

• Frequency

Reciprocal of the period of a sinusoid.

• Inverse relation (of the relation R)

A relation that consists of all ordered pairs b, a for which a, b belongs to R.

• Logarithm

An expression of the form logb x (see Logarithmic function)

• Major axis

The line segment through the foci of an ellipse with endpoints on the ellipse

• Outcomes

The various possible results of an experiment.

• Probability distribution

The collection of probabilities of outcomes in a sample space assigned by a probability function.

• Pythagorean identities

sin2 u + cos2 u = 1, 1 + tan2 u = sec2 u, and 1 + cot2 u = csc2 u

• Sample standard deviation

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

• Sample survey

A process for gathering data from a subset of a population, usually through direct questioning.

• Square matrix

A matrix whose number of rows equals the number of columns.

• Tree diagram

A visualization of the Multiplication Principle of Probability.

• Unit ratio

See Conversion factor.

• 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.
