This Texas Instruments calculator is approved for use on the SAT and PSAT exams, as well as AP tests.
Those taking courses such as Chemistry and Physics will find this functionality helpful since it helps students discover the theory that drives equations. The graphing calculator's CAS functionality, or “Computational Algebra System," allows you to manipulate equations and solve for any variable within the equation. Even more, you have the ability to enter equations in proper notation-with superscript and subscript. It's also possible to create documents and pages and store them the way you would with a computer. You can even import digital images and place graphs and equations on them. The Texas Instruments Nspire CX CAS graphing calculator features advanced functionality for students taking advanced high school coursework and university students in math, science, and engineering classes. The FX-9750GII requires four AAA batteries and includes built-in USB functionality for connecting with other devices. Speaking of test time, test takers can also benefit from the Casio graphing calculator-it’s approved for use on the PSAT, SAT, and college entrance exams, as well as AP tests. The high-speed CPU processes lengthy calculations and complex graphs quickly and accurately, which is essential during test time when every second counts. The high-resolution LCD display includes enlarged-dot area technology that enhances the visuals-lines and curves are sharp and easier to see and comprehend. The FX-9750GII also includes several soft-menus to easily access functionality for common tasks. The icon-based menu makes it easy for students to navigate.
He has a Bachelorof Arts in Mathematics from the State University of New York at Buffalo and isworking on the completion of his Masters in Physics Education at Buffalo StateCollege.The Casio FX-9750GII Graphic Calculator features all the basic functionality of an entry-level graphing calculator, making it great for math coursework from Pre-Algebra to AP Calculus and Statistics and courses in between (like Geometry and Trigonometry). The TIcalculators do not use common sense when performing calculations, so thestudents need to correctly input the data to get the correct outcomes.ĭavid Doty is currently teaching NYS Regents Physics,Environmental Science, and various science laboratories at Salamanca Cit圜entral Schools. Manystudents use the Texas Instrument calculators (TI 83 and TI 83+) as a tool forsolving problems and we need to clarify the problems that students have inusing this tool. This is the orders of operations that the TI follows for this example:Īlthoughone of the goals of the new NYS standards is to increase conceptualunderstanding of physics, students still need to be able to mathematicallysolve physics problems. However if a student mistakenly types in: In a vacuum, the wavelength of green light is 5 X 10 -7meter. Asan example look at question 3 from the sample physics problems. This becomes problematic when dividingnumbers in scientific notation. Theproblem with typing in 10 (exponent) is that the TI 83 calculators donot distinguish scientific notation from multiplication and division. 030 įor those of you who do not want to use the EE buttonon the calculator, yes parentheses can be used to enter equations.
