Get ride of the glass and don't do it again. Being an extremely cool teacher, he said something to the effect of, "I know what you're doing, but you had to use physics to make it work, so I'll let it slide once. The teacher said one day he looked up from his desk during a test and noticed a bunch of mirrors and prisms strewn about the room with students carefully aiming their calculators. HP's did infrared communications whereas TI typically requires a physical cable to "network" between devices. Of course any smart phone today could run Derive in a DOS emulator and probably still have enough cycles left over to play Angry Birds, but that would make math "too easy." Can't have that.įunny story: Talked to a physics teacher (high school level) ages ago in a school where they standardized on HP's line rather than TI's. Far better to keep them busy doing busy work. It also replaces the conventional AAA cells with a rechargeable battery pack. Finagle forbid they actually spend braincycles on solving a problem and leave the arithmetic to something that's designed to crunch numbers quickly and correctly. The TI-84 Plus C Silver Edition is based on the original TI-84 Plus Silver Edition, with a new backlit color display added and software enhancements to take advantage of it, such as highlighting different functions on a graph in different colors for easier comprehension. Anything with a radio is verboten as a matter of course, and likewise anything "too powerful" isn't allowed. Because teachers are paranoid the chill'ins will cheat in class.
