Thank you for the advice. John P you are right in Algebra it's taught to rationalize the denominator but once Calculus comes around that rule is not forced on students. Just like in Algebra courses improper fractions are accepted as answers yet, in Elementary school improper fractions were frowned upon. That's why on Wolfram Alpha and Texas Instruments CAS Calculators and Casio Classpad the denominator is allowed to have a radical when seeking a derivative. Plus, I'll have to brush up on my programming skills for this calculator. I should have done my research before purchasing this calculator. I love the hardware for this calculator though. HP could earn a customer for life if they'd look into my complaints and resolve my issue with a sensible option in the settings menu.
