You're right, graphing there are a few, but non-graphing... it ain't any . Just the 15C and the 42S. The TI 68 has comprehensive complex support but no matrices. Neither had the Casio FX 580, although it had slightly better than usual complex for a Casio scientific. May I suggest that you make your students do it by hand? It's quite easy, maybe tedious but also very instructive. You'd be amazed at the things they have trouble with. And if you're lucky and they have no trouble with the chores, using a non-CAS graphing one capable of this should be tolerated IMHO. |
