Hello What is the standard definition of a polynomial? according to the book I am using a polynomial is an algebraic expression which is integral and rational for all the terms. It gives no definition of integral or rational seperately, but I think integral means that the variables are to powers of integers and not fractions such that a/b and b=/= 1 basically non whole numbers What does rational mean? And the degree of a polynomial? Schaumms outline says it is the sum of all the exponents of variables. But my school taught that its the value of the variable with greatest exponent. Dont know if thread belongs here. Sorry if wrong section.
