Key Calculus Terms and definitions covered in this textbook
• Angle

Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

• Angle between vectors

The angle formed by two nonzero vectors sharing a common initial point

• Annual percentage rate (APR)

The annual interest rate

• Coefficient matrix

A matrix whose elements are the coefficients in a system of linear equations

• Common difference

See Arithmetic sequence.

• Compound fraction

A fractional expression in which the numerator or denominator may contain fractions

• Direction angle of a vector

The angle that the vector makes with the positive x-axis

• Domain of a function

The set of all input values for a function

• Graphical model

A visible representation of a numerical or algebraic model.

• Inequality symbol or

<,>,<,>.

• Main diagonal

The diagonal from the top left to the bottom right of a square matrix

• Position vector of the point (a, b)

The vector <a,b>.

• Positive angle

Angle generated by a counterclockwise rotation.

• Reduced row echelon form

A matrix in row echelon form with every column that has a leading 1 having 0’s in all other positions.

• Reflection across the x-axis

x, y and (x,-y) are reflections of each other across the x-axis.

• Row echelon form

A matrix in which rows consisting of all 0’s occur only at the bottom of the matrix, the first nonzero entry in any row with nonzero entries is 1, and the leading 1’s move to the right as we move down the rows.

• Secant

The function y = sec x.

• Standard unit vectors

In the plane i = <1, 0> and j = <0,1>; in space i = <1,0,0>, j = <0,1,0> k = <0,0,1>

• Stem

The initial digit or digits of a number in a stemplot.

• Transverse axis

The line segment whose endpoints are the vertices of a hyperbola.
