Equation means an equality between two expressions in algebraic language, which includes letters—handled just like numbers—to represent unknown quantities involved in relationships between quantities, and which is true only for some values of the unknown(s) (see Drouhard & Teppo, 2004)....
an algebraic expression is an expression which consists of variables and constants. in expressions, a variable can take any value. thus, the expression value can change if the variable values are changed. but algebraic identity is equality which is true for all the values of the variables. q3...

The last two terms introduced trigonometric expressions in order to increase the nonlinearity into the overall expressions. This strategy could avoid very high degree polynomial terms and Journal of Applied Pharmaceutical Science 01 (03); 2011: 57-61 reduce the parameters to within 30 terms with ...
Appendix A: Proof of σ(ε(i,K)i↔j)=σ(ε(j,K)j↔i) in (63) and related expressions With no real loss of generality, assume that i<j and let K be an index set that does not include i and j. We can then write the set K as the union of three disjoint subsets as dep...
7. How to check algebraic identifiers? Algebraic identification can be easily verified in two ways. One method is substitution math in which we replace the value to find the variable in the algebraic identifier. Algebraic identities have multiple expressions on both sides of the signed equation. ...
