I’ve been looking everywhere for a function/method for the graphic calculator (TI-83 Plus) so it would calculate the cross product of two vectors. Each vector is 1x3.

I realized that everybody at school just uses calculator today, while I’ve been doing it by hand my whole life. I haven’t got the chance to ask anybody yet and this homework crap is due tomorrow.

Anybody got ideas?
