Zusammenfassung: I'm a new physics teacher, having retired from a 30 year career as a technology company executive, and I'm no stranger to portable electronic devices. I was looking among the many Amazon reviews to decide what model of graphing calculator would best meet my needs . . .
Exzerpt: This is exactly what was required by our school district, but TI designed the charging port so poorly that it didn't even last a year. And the design of the rechargeable battery prevents use of anything BUT their battery and that port!
Zusammenfassung: Superb calculator. Using it for Calculus, however it has more advanced options. It does integration and derivatives automatically! I like the ease of use and straight-forward controls. I don't like the auto scroll button or arrow keys. They are too sensitive and often lead to accidental clicks.
