Best Graphing Calculator for Students

Posted 1 year ago - Bestcovery's experts have ranked this the #1 Best Graphing Calculator for Students and #1 Best Calculator Overall. TI's Motorola 68000-based TI-89 provides a built-in computer algebra system akin to computer software such as Mathematica and Maple. It can simplify mathematical expressions and perform partial fraction decomposition, useful for some intermediate calculus classes. Basic algebra, systems of equations, limits, derivatives, and integrals are also possible and can be performed symbolically. It can plot most anything including 2D, parametric, polar, and differential equations. Unfortunately it is too powerful to be allowed on the ACT exam, although it works for the SAT and AP Calc. It's a little more expensive than the others and if you're not past the ACT you probably don't need a calculator this advanced. The TI-89 does support USB for downloading programs. - Read Full Review

Texas Instruments TI-89 | Titanium version

Posted 1 year ago - The TI-89 is a popular graphing calculator made by Texas Instruments, originally released in 1998. It features powerful computer algebra system (CAS) that can solve albebraic expressions in symbolic terms; most other calculators solve in terms of number only. For example, entering (x^3-x^2-8x+12)/(x+3) returns x2 − 4x + 4, which is pretty printed by default. The current version of the calculator that is sold in stores is the TI-89 Titanium model, released in 2004 to replace the popular original TI-89. In the United States, the TI-89 is allowed by the College Board on all calculator-permitted tests, including the SAT, however it is banned from some other tests and classrooms because of its advanced function. The retail price of this calculator is $150. Features Motorola 68000 32-bit microprocessor running @ 10, 12, or 16 MHz (depending on hardware version) Algebraic factoring of expressions Algebraic simplification (CAS) Evaluation of trigonometric expressions to exact values Equation solving for a certain variable (CAS) Finding limits ... PROS: (1) Includes powerful computer algebra system (CAS) that can manipulate expressions symbolically (2) The most powerful calculator that can be legally used in most testing situations (3) Nicely notes any errors or conditions when solving equations (ex: "Excludes imaginary solutions") (4) Includes excellent built-in apps, and can be upgraded to more apps (5) Includes EEPro electrical engineering app ... CONS: (1) Fairly expensive if not used to full capacity of graphing and CAS (2) Can be challenging to master (3) The full capabilities arent realized until upper level mathematics courses in University - Read Full Review
