Solve example on various calculators

[lrdheat]

I am wondering why the SolveN and Solve on the non CAS CASIO 9750giii manage to produce all 3 results, SolveN the -1 and -.41… roots, Solve the 2.41… roots. The TI 30X MathPrint is a nice calculator. I discovered that the max( and min( commands can be used in a function in an integration such as Integral from 0 to pi/4 of (max( sin (x), cos (x)). Pretty neat! By the way, the polynomial method works on the CASIO 991CW as well, and the more fancy CASIO’s! I like how the TI retains the history when turned off. The 991CW loses it’s history but retains statistics data.
