Key Calculus Terms and definitions covered in this textbook
• Commutative properties

a + b = b + a ab = ba

• Complex conjugates

Complex numbers a + bi and a - bi

• Ellipsoid of revolution

A surface generated by rotating an ellipse about its major axis

• Even function

A function whose graph is symmetric about the y-axis for all x in the domain of ƒ.

• Explanatory variable

A variable that affects a response variable.

• Focal axis

The line through the focus and perpendicular to the directrix of a conic.

• Geometric series

A series whose terms form a geometric sequence.

• Heron’s formula

The area of ¢ABC with semiperimeter s is given by 2s1s - a21s - b21s - c2.

• Line of symmetry

A line over which a graph is the mirror image of itself

• Linear regression

A procedure for finding the straight line that is the best fit for the data

• Magnitude of a vector

The magnitude of <a, b> is 2a2 + b2. The magnitude of <a, b, c> is 2a2 + b2 + c2

• Multiplication principle of counting

A principle used to find the number of ways an event can occur.

• Multiplicative inverse of a real number

• Perpendicular lines

Two lines that are at right angles to each other

Any one of the four parts into which a plane is divided by the perpendicular coordinate axes.

• Transitive property

If a = b and b = c , then a = c. Similar properties hold for the inequality symbols <, >, ?, ?.
