College has strict requirements sometimes (Score 0)

I graduated from the College of Engineering at the University of Cincinnati not to long ago. For both our calc and physic classes, we were pretty much limited to a TI-89 or TI-92. You could use below the TI-89, but it didn't have enough functions for the higher level calc, so it was pretty useless. I do remember some students would bring in other makes and most times (not always) they were not permitted to use them. The professors said they didn't know the models and were afraid they might have additional features which would permit cheating. Also don't go to high in the TI line-up. Some also come with keyboards, which everytime a student came in the room with those, the calc was banned. The TI-92 was pretty much the safest calculator which had everything you needed for both physics, calc IV, and beyond.

Once you get into signal processing, you will be using matlab or equivalent software.
