Why is graphing calculator so expensive?ĭue to the high market price caused by high demand, he guesses that the company can boast a profit margin of over 50 percent. Is the TI-Nspire CX II allowed on Act?ĭo you find this helpful? The TI-Nspire CX handheld is permitted for use SAT*, AP*, PSAT/NSMQT*, IB®, and ACT® college entrance exams, as well as many state standardized tests. We would strongly encourage most people to go with the CAS version as it is just downright more capable and around the same price. If you want to be able to use your calculator on the most possible standardized tests, you are safer going with the TI-nspire CX. Can you do limits on a TI-Nspire CX?Ī calculator like the TI-Nspire (or any other calculator with CAS - Computer Algebra System) can actually do that limit problem (and all sorts of much more difficult calculus problems) and give you the exact answer.
The ACT, which competes with the College Board for test-takers, prohibits calculators with CAS functionality. Seven models of the TI-Nspire CAS are on the College Board’s list. The CAS version is not allowed on ACTs but is allowed on SATs. I have also had the NSpire CX (NOT CAS) This was by due to its acceptance on all standardized testing. I have owned a TI-85 84 84plus 89 and 92. The TI Nspire CX CAS is the absolutely hands down best calculator on the market today. If you’re unaware of what a CAS calculator is, it is a Computer Algebra System calculator. TI-Nspire CX II CAS, the difference is that TI-Nspire CX II CAS has a computer algebra system (CAS), meaning it can do algebraic operations, while the TI-Nspire CX does not. What is the difference between TI Nspire CX II and CX II CAS? How do you put infinity on a TI Nspire CX?
