Hi - I’m currently an Electrical Engineering Technology student at WCTC planning to transfer to MSOE after completing my associates in order to earn a B.S.E.E. I’m looking to upgrade my calculator from a TI-84 Plus to either the TI-89 Titanium or the TI-Nspire CX CAS. My main concern is that I purchase a calculator that is not only capable of performing the necessary functions for electrical engineering (complex matrices, polar to rectangular conversions, etc.) but in addition to this, will be allowed in the upper division electrical engineering courses my Junior and Senior year at MSOE. Any suggestions as to which calculator (if either) would be acceptable? Any recommendations would be appreciated!
Most professors will teach their courses using a TI-89, but I have seen several EE students using a TI-Nspire. If you are able to figure out how to find and use the necessary functions on a TI-Nspire then you should be fine using it. But I do believe most students use a TI-89 and are able to easily follow instructions from professors.
