Sentence See MATHEMATICAL SENTENCE. sequence Any ordered SET or list of quantities. The items in a sequence are called TERMs. GLOSSARY 36 rule method of specification – sequence series – solving the equation series The SUM of a specific SET of sequentially ordered TERMs. set Any collection of numbers, objects, or elements. Sets are usually identified by capital letters. For example, if a set called A consists of the numbers 2, 4, 6, and 8, it is identified as A = {2, 4, 6, 8}. sigma notation (summation notation) Derived from the 18th letter of the Greek alphabet, this symbol Σ is used to represent the SUM of all the values in an ARITHMETIC SEQUENCE.
A common VARIABLE used in algebra to signify an unknown quantity. 2. The variable used to signify the HORIZONTAL LINE in a Cartesian GRAPH (x-axis). x-axis The HORIZONTAL AXIS (horizontal NUMBER LINE) in a CARTESIAN COORDINATE SYSTEM graph. POSITIVE NUMBERs are to the right of the ORIGIN on the x-axis, and NEGATIVE NUMBERs are to the left of the origin on the x-axis. vertical line Vertical line x-intercept The point on a GRAPH in which a LINE SEGMENT intersects the x-axis, which is when y = 0. vertex – x-intercept GLOSSARY 43 GLOSSARY y-axis – Zero Product Property y-axis The VERTICAL AXIS (vertical NUMBER LINE) in a CARTESIAN graph.
Independent variable The VARIABLE in a direct variation formula that does not rely on the other variable for its value. For example, in y = kxn, y is the DEPENDENT VARIABLE, and x is the independent variable. index A number or variable used in ROOTs and POWERs to indicate the power of a quantity. For example, when taking a root of a number, as − 3− in √ 9 the index is 3; if no root is indicated, as in √25, the index is 2 (for the SQUARE ROOT). When raising a number to a power, as in 42, the index is 2; in 43, the index is 3, and so on, and in this case the index is often called the EXPONENT or the power.
