Do You Dare/Care to Try These Out?
Since last week's review focused on several free online calculators, it is appropriate to mention other on-line calculators (FREE or relatively inexpensive).
Note that I am only providing these links (via SoftSea.com reviews), which is not equivalent to recommending them. Most of them I have not used or downloaded. Thus, check them out...and let me know if they are great or problematic.
Trying to provide a variety of options, my list is:
Play with them...Let me know the plus and minus aspects.
- ecalc has algebraic/RPN modes, does unit conversions, solves equations, and computes complex-numbers...plus has versions for iGoogle user and Google gadget.
- BlueMATH calculator is both a desktop calculator and a mathematics expression evaluator, plus can calculate multiple expressions simultaneously.
- WozGraph mimics hand-held graphing calculators, allowing you to create, save, and print graphs.
- CalculatorX calculates values of expression that include arithmetic, logical, bitwise and relational operations.
- BlitzCalc computes with mathematical, arithmetical, trigonometric, and statistical functions.
- DreamCalc Calculator mimics hand-held calculators, including graphing, data plots, RPN and algebraic modes, and a polynomial solver.
- XICalc computes integers with precision to millions of digits, works in base 2 to base 36, and performs number theory operations (GCD, Modulo arithmetic, Boolean functions, random number generator, prime factoring, phi/sigma/tau function)
- CrazyMath acepts sequences of expressions as you would write them on paper, plus graphs 2D/3D functions.
- WIRIS Desktop includes both a CAS (Computer Algebra System) and a DGS (Dynamic Geometry System), plus calculates integrals and limits, graphs 2D/3D functions, and manipulates matrices.
- Matrix Calculator performs basic matrix operations plus those involving transposes, inversions, scaling, determinants, traces, and adjoints.
Again, if you use other on-line tools that are FREE or inexpensive, please send me their links so that I can possibly pass them on to other mathematics teachers.
