Irrational EquationsDate: 06/02/2002 at 16:53:15 From: Brad Strickland Subject: Irrational Equations I am having serious trouble finding ANYTHING on irrational equations. I have used up all the books my library had on anything relating to math and no websites seem to have any information on them. If you could take a moment to tell me what they are and perhaps how to go about solving them, I would be most appreciative.

A rational equation is one involving a ratio of expressions, that is, one expression (such as a polynomial) divided by another. But there is no sensible way to give a meaning to "irrational equation" in the same way -- an equation that does NOT involve ratios, perhaps? In a quick Web search for the phrase "irrational equation", the only mathematical references I found were in lists of topics covered in high school algebra courses. Thus it appears that this is a pedagogical term only, not one that mathematicians use in the "real world" (after graduation). The closest I could see to a definition is something like "an equation involving radicals". I would not use the term "irrational equation" for this; I'd just say "radical equation". If this is what the term means, then it's a rather broad category and no one method will always work. You can search the Dr. Math Archives, http://mathforum.org/library/drmath/mathgrepform.html for items using the words "radical" and "equation", or "root" and "equation", and some of the items you find will give methods for solving particular "irrational equations".

Thanks for your help, you have saved me countless hours :] By the way, http://www.purplemath.com/modules/solvrad.htm looks to be a good linking page if anyone asks about this again. Thanks again. |
