[Bug]-Missing root in solving equation

[Helge Gabert]

Yes, that is nice that the TI family of calculators can apparently solve this equation for all roots on its domain!

However, I am not aware of any algorithm which returns all roots (globally, and guaranteed!) on the entire domain of any arbitrary real function (not just a polynomial), which may also be complex-valued. If such an algorithm existed, and if it could be easily implemented, and if it wouldn't be too slow, I'm sure the HP Prime CAS system would have it incorporated.

I don't own any TIs, so I can't give you a counter example, but I'm sure there is a function or two where "even" a TI calc will have to pass, i.e., not finding all global roots. Maybe somebody can come up with one . . .
