Key Calculus Terms and definitions covered in this textbook
• Algebraic expression

A combination of variables and constants involving addition, subtraction, multiplication, division, powers, and roots

• Ambiguous case

The case in which two sides and a nonincluded angle can determine two different triangles

• Arctangent function

See Inverse tangent function.

• Convergence of a series

A series aqk=1 ak converges to a sum S if imn: q ank=1ak = S

• Cosine

The function y = cos x

• Extracting square roots

A method for solving equations in the form x 2 = k.

• Frequency (in statistics)

The number of individuals or observations with a certain characteristic.

• Intermediate Value Theorem

If ƒ is a polynomial function and a < b , then ƒ assumes every value between ƒ(a) and ƒ(b).

• Leibniz notation

The notation dy/dx for the derivative of ƒ.

• Lemniscate

A graph of a polar equation of the form r2 = a2 sin 2u or r 2 = a2 cos 2u.

• Limit at infinity

limx: qƒ1x2 = L means that ƒ1x2 gets arbitrarily close to L as x gets arbitrarily large; lim x:- q ƒ1x2 means that gets arbitrarily close to L as gets arbitrarily large

• Normal curve

The graph of ƒ(x) = e-x2/2

• Parametric equations for a line in space

The line through P0(x 0, y0, z 0) in the direction of the nonzero vector v = <a, b, c> has parametric equations x = x 0 + at, y = y 0 + bt, z = z0 + ct.

• Product of matrices A and B

The matrix in which each entry is obtained by multiplying the entries of a row of A by the corresponding entries of a column of B and then adding

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

A function that can be written in the form ƒ(x) = ax 2 + bx + c, where a, b, and c are real numbers, and a ? 0.

• RRAM

A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the right-hand end point of each subinterval.

• Subtraction

a - b = a + (-b)

• Unbounded interval

An interval that extends to -? or ? (or both).
