Texas Instruments Graphing Editorial Review
The Texas Instruments TI-89 Titanium Graphing Calculator has received mixed reviews from customers. The calculator is programmable, so students should check with their teacher/professor or syllabus to see if it's allowed in class. However, it is permitted for use on the SAT exam. The calculator has a good display and smooth buttons, making it great for calculus and highly recommended by engineers. It is also affordable compared to the price of new calculators. On the downside, some functions do not work or work incorrectly and the refurbished model does not come with any connections. Additionally, one customer reported a screen freezing issue, but the seller was helpful in resolving the issue.
