Key Calculus Terms and definitions covered in this textbook
• Arccotangent function

See Inverse cotangent function.

• Cube root

nth root, where n = 3 (see Principal nth root),

• Ellipse

The set of all points in the plane such that the sum of the distances from a pair of fixed points (the foci) is a constant

• Equivalent vectors

Vectors with the same magnitude and direction.

• Half-angle identity

Identity involving a trigonometric function of u/2.

• Inverse variation

See Power function.

• Invertible linear system

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

• Logarithmic regression

See Natural logarithmic regression

• Matrix element

Any of the real numbers in a matrix

• Midpoint (on a number line)

For the line segment with endpoints a and b, a + b2

• Natural logarithm

A logarithm with base e.

• Polar coordinates

The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

• 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

• Semiminor axis

The distance from the center of an ellipse to a point on the ellipse along a line perpendicular to the major axis.

• Sinusoidal regression

A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

• Standard form: equation of a circle

(x - h)2 + (y - k2) = r 2

• Sum of a finite arithmetic series

Sn = na a1 + a2 2 b = n 2 32a1 + 1n - 12d4,

• Supply curve

p = ƒ(x), where x represents production and p represents price

• Union of two sets A and B

The set of all elements that belong to A or B or both.

• Velocity

A vector that specifies the motion of an object in terms of its speed and direction.
