Key Calculus Terms and definitions covered in this textbook
• Augmented matrix

A matrix that represents a system of equations.

• Compounded annually

See Compounded k times per year.

• Compounded k times per year

Interest compounded using the formula A = Pa1 + rkbkt where k = 1 is compounded annually, k = 4 is compounded quarterly k = 12 is compounded monthly, etc.

• Constant function (on an interval)

ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

• Distance (in Cartesian space)

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

• equation of a quadratic function

ƒ(x) = ax 2 + bx + c(a ? 0)

• First quartile

See Quartile.

• Gaussian curve

See Normal curve.

• Origin

The number zero on a number line, or the point where the x- and y-axes cross in the Cartesian coordinate system, or the point where the x-, y-, and z-axes cross in Cartesian three-dimensional space

• Point-slope form (of a line)

y - y1 = m1x - x 12.

• Polar coordinate system

A coordinate system whose ordered pair is based on the directed distance from a central point (the pole) and the angle measured from a ray from the pole (the polar axis)

• Product of a scalar and a vector

The product of scalar k and vector u = 8u1, u29 1or u = 8u1, u2, u392 is k.u = 8ku1, ku291or k # u = 8ku1, ku2, ku392,

The distance from a point on a circle (or a sphere) to the center of the circle (or the sphere).

• Reflexive property of equality

a = a

• Speed

The magnitude of the velocity vector, given by distance/time.

• Sum of an infinite series

See Convergence of a series

• Translation

See Horizontal translation, Vertical translation.

• Vertical line test

A test for determining whether a graph is a function.

• Ymin

The y-value of the bottom of the viewing window.

• z-coordinate

The directed distance from the xy-plane to a point in space, or the third number in an ordered triple.
