what usage do algebraic fractions (monomial or polynomial) have in our life? Are there specific professions that deal with them now and then? Where exactly in technology do they have their very own place?
What I'm looking for is very concrete examples.
Just for clearification: with algebraic fractions (monomial or polynomial) I mean terms such as:
$T_1(x)= \frac{3x + 5}{x^2-7}; T_2(x)=\frac{5}{3x-1} $ etc.
