Want to know what all those buttons on your calculator do? Come to the premier lecture for Engineering Tools. Everyone is invited at no cost to you. The instruction will cover the TI-89 Titanium and the HP 50g. If you have a slightly older model without the shine (TI-89 or HP 49g+), you are still encouraged to come.
If you're looking forward to getting a head start, you should investigate the web page Dr. Urroz has prepared for the seminar.
This seminar is part of Engineering Tools: a free lecture series dedicated to teaching you how to use all the software you are expected to know but were never taught.
