Key Calculus Terms and definitions covered in this textbook
• Base

See Exponential function, Logarithmic function, nth power of a.

• Constant of variation

See Power function.

• Cosecant

The function y = csc x

Facts collected for statistical purposes (singular form is datum)

• Graph of a polar equation

The set of all points in the polar coordinate system corresponding to the ordered pairs (r,?) that are solutions of the polar equation.

• Histogram

A graph that visually represents the information in a frequency table using rectangular areas proportional to the frequencies.

• Inverse composition rule

The composition of a one-toone function with its inverse results in the identity function.

• Irreducible quadratic over the reals

A quadratic polynomial with real coefficients that cannot be factored using real coefficients.

• Logistic regression

A procedure for fitting a logistic curve to a set of data

• Magnitude of an arrow

A rectangular array of m rows and n columns of real numbers

• Polar distance formula

The distance between the points with polar coordinates (r1, ?1 ) and (r2, ?2 ) = 2r 12 + r 22 - 2r1r2 cos 1?1 - ?22

• Quantitative variable
