Solve crash

[lrdheat]

Perhaps oddly, Prime and IPad Prime successful with solving diff(f(x)) to equal 0, quickly finds exact solutions of -1, 1/244

Above and earlier posts all in CAS

Indeed, in HOME, if a decimal is entered after an integer in this problem, the Prime platforms do find the 3 decimal solution approximations with solve(

Without the decimal, even in HOME, the problem produces the freeze in the physical Prime, the crash on the iPad.

Great example, however, of the difficulty some problems present a non CAS when a function is very flat near an extremum, interesting to see a wrong answer vs can't find root response on various platforms.

Also interesting to see the nSpire produce an erroneous answer (-3.789 vs correct -1.92 for f(x) roots...

Fascinating behavior, and a reminder that these platforms are tools to a solution, but should not be used/viewed as a perfect black box in producing solutions.
