DALLAS, Jan. 27, 2015 - Texas Instruments (TI) (NASDAQ: TXN), the most trusted brand in graphing calculator technology, today unveiled a new addition to the TI-84 Plus family of graphing calculators—the TI-84 Plus CE graphing calculator. The TI-84 Plus CE is now 30 percent thinner and 30 percent lighter than the TI-84 Plus, and students can express their own personal style by choosing their TI-84 Plus CE from a variety of colors, such as red, hot pink and blue.
TI created the TI-84 Plus CE in response to feedback from students using earlier models of the TI-84 Plus. "Students asked us to make their go-to graphing calculator slimmer, sleeker, more colorful, and lightweight, and we answered with the modern, streamlined design of the TI-84 Plus CE," said Peter Balyta, Ph.D., president of TI Education Technology. "Once you hold the new TI-84 Plus CE in your hand, you will immediately see and feel the improvements."
The TI-84 Plus CE has six times the memory of the TI-84 Plus so students can store vivid, full-color graphs, images and data. The lightweight yet durable design also makes the graphing calculator easier to carry to and from school and activities for today's on-the-go students.
Teachers will appreciate that the key placement, navigation and menus are the same as earlier TI-84 Plus models so they can continue to use their current classroom activities. Parents will appreciate that a one-time purchase of a TI-84 Plus CE in middle school will take students through all of the math courses they need to take in high school, college and beyond– including algebra, geometry, calculus and statistics.
The TI-84 Plus CE graphing calculator is permitted on high-stakes exams, including the PSAT/NMSQT*, SAT* and ACT® college entrance exam as well as Advanced Placement* exams that allow or require a graphing calculator. The TI-84 Plus CE will be available for purchase later this spring. For information on availability, visit our website.

Toutefois, nous remarquions apparemment un bug empêchant d'obtenir des résultats exacts dans le contexte d'exponentielles complexes. 
Il est donc possible de récupérer une forme exacte perdue suite à des résultats intermédiaires non gérés par le moteur ! 
L'on peut également s'occuper des bugs du moteur exact intégré dans le cas d'exponentielles complexes : 
obtention de la mesure principale d'angles exprimés en radians ! 
calculs avec des exponentielles ! 
calculs avec des logarithmes ! 
gestions des formes $mathjax$\sqrt{\pm\frac{a}{b}\pm\frac{{c}\sqrt{d}}{e}}$mathjax$, ouvrant entre autres la voie à de nouvelles possibilités en trigonométrie !
