Key Calculus Terms and definitions covered in this textbook
• Blind experiment

An experiment in which subjects do not know if they have been given an active treatment or a placebo

• Divergence

A sequence or series diverges if it does not converge

• Domain of validity of an identity

The set of values of the variable for which both sides of the identity are defined

• Explicitly defined sequence

A sequence in which the kth term is given as a function of k.

• Identity function

The function ƒ(x) = x.

• Inverse tangent function

The function y = tan-1 x

See Polynomial function in x.

• Logistic regression

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

• Negative angle

Angle generated by clockwise rotation.

• Obtuse triangle

A triangle in which one angle is greater than 90°.

• Ordered set

A set is ordered if it is possible to compare any two elements and say that one element is “less than” or “greater than” the other.

• Projection of u onto v

The vector projv u = au # vƒvƒb2v

• Quotient identities

tan ?= sin ?cos ?and cot ?= cos ? sin ?

• Slant line

A line that is neither horizontal nor vertical

• Solve algebraically

Use an algebraic method, including paper and pencil manipulation and obvious mental work, with no calculator or grapher use. When appropriate, the final exact solution may be approximated by a calculator

• Standard representation of a vector

A representative arrow with its initial point at the origin

• Sum of two vectors

<u1, u2> + <v1, v2> = <u1 + v1, u2 + v2> <u1 + v1, u2 + v2, u3 + v3>

• Summation notation

The series a nk=1ak, where n is a natural number ( or ?) is in summation notation and is read "the sum of ak from k = 1 to n(or infinity).” k is the index of summation, and ak is the kth term of the series

• Terminal point

See Arrow.

• yz-plane

The points (0, y, z) in Cartesian space.
