If you just beginning to calculate students often find themselves with a face with a question on their graphing calculator. Should acquire a CAS, or computer algebra system, calculator? If you do not understand what a CAS-enabled computer, do not make an informed decision about whether or not to buy one.
A graphing calculator standard can only perform calculations with numbers. That is, you can divide, multiply, add and subtract as well as complete offmore complex operations such as logarithms, trigonometric functions, radicals, etc. However, a standard graphing calculator is not capable of operations on variables.
On the other hand, allows a computer algebra system graphing calculator is capable of much more. It 'can manipulate variables like x and y. This means it has the ability to factor polynomials, solve equations, calculus of functions such as derivatives and solved without numerical limits. They are so powerful thatsome teachers do not allow them, and were banned by some evidence, such as the ACT. You are allowed two tests very large, but the test of the SAT and AP Calculus. For many students, it is enough for them to decide they want one.
If you buy a graphing calculator allowed to go to CAS, you must ensure that a well informed buyer. Texas Instruments is the most prolific producer of graphing calculators on the market. As such, most students will choose,buy a TI. TI was able to do more than one CAS models to consider. The TI-89 Titanium, TI-Voyage 200 and TI-Nspire CAS everyone has a computer algebra system. Because the TI-Voyage has a QWERTY keyboard, is prohibited by almost all standardized tests. This means that for most students is a decision by comparing the TI-Nspire CAS vs TI-89 Titanium.
The TI-89 Titanium is not so modern. It 'been around for over 10 years, but still feels quite modern compared to most otherCalculator time. TI-Nspire CAS is the latest and greatest from Texas Instruments. It 'displays with high resolution, similar to modern computer interface and create documents. Whatever you choose always, you are sure you have done your homework. These computers cost more than $ 100, and does not want to have regrets. Spend some 'time online checking out both options, see what your friends say, and you are sure to be a decision you make is to come for many years.
