Damnit, I may have been affected by this problem. Apparently, some log() or ln() functions return faulty answers. I believe the TI 30 line, TI 40 and TI 34 line are affected. My university does not allow graphing calculators but I don't believe these are affected.
Anyhow, here's the link [L]http://www.ti.com/calc/docs/statement.htm[/L].
