Key Calculus Terms and definitions covered in this textbook
• Acute triangle

A triangle in which all angles measure less than 90°

• Arcsine function

See Inverse sine function.

• equation of an ellipse

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

• Intercepted arc

Arc of a circle between the initial side and terminal side of a central angle.

• Inverse sine function

The function y = sin-1 x

• Linear correlation

A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

• Measure of center

A measure of the typical, middle, or average value for a data set

• Negative angle

Angle generated by clockwise rotation.

• nth root

See Principal nth root

• One-to-one rule of exponents

x = y if and only if bx = by.

• Orthogonal vectors

Two vectors u and v with u x v = 0.

• Parabola

The graph of a quadratic function, or the set of points in a plane that are equidistant from a fixed point (the focus) and a fixed line (the directrix).

• Permutation

An arrangement of elements of a set, in which order is important.

• Right-hand limit of ƒ at x a

The limit of ƒ as x approaches a from the right.

• Series

A finite or infinite sum of terms.

• Simple harmonic motion

Motion described by d = a sin wt or d = a cos wt

• Slant line

A line that is neither horizontal nor vertical

• Unit vector in the direction of a vector

A unit vector that has the same direction as the given vector.

• Vertices of an ellipse

The points where the ellipse intersects its focal axis.

• x-coordinate

The directed distance from the y-axis yz-plane to a point in a plane (space), or the first number in an ordered pair (triple), pp. 12, 629.
