Graphmatica is a powerful equation plotter with numerical and calculus features. Graph Cartesian functions, relations, and inequalities, plus polar, parametric, and ordinary differential equations. Up to 25 graphs on screen at once. Offers copy to clipboard (bitmap and WMF), Button Bar, on-line help and demo files. In summary, a great tool for students and teachers of anything from high-school algebra through college calculus.
Yes - 30 day timeout
- The Windows version is now compiled with Unicode support. This means you can use both Greek and Roman characters, as well as an extended set of superscript exponents, subscripts, and mathematical operations as you like in annotations, graph titles, and
- Added special characters tool dialog to make it easier to enter Greek letters, super- and subscript numerals, and authentic math operators like times sign and division without using Character Map or memorizing keycodes
- Added support for Greek letters and subscripts in function and constant names. (So you can now define constants as the single letters alpha, beta, etc. and use the Greek letter pi instead of Roman "p" or "pi".)
- The sum and gamma/gammaln functions can now also be specified using the Greek capital letters sigma and gamma, respectively
- The Functions and Constants dialog now properly prohibits you from defining inaccessible duplicate functions (or redefining built-in functions or constants) whose names differ only by the case of Latin letters used. Also, semantic errors in functions (m
- Fixed bugs introduced in 2.1 preventing ODE systems from graphing and impeding use of the sum() function without explicitly defining the domain of the index variable n
- The alternate-notation ODE system variables x1...x4 and dx1...dx4 can now be specified using Unicode subscripts instead of plain numerals
- Open-ended domains for Cartesian equations can now be specified explicitly using the Unicode "infinity" symbol instead of just leaving that part of the domain specification blank
- Fixed potential crash on deleting piecewise-defined equations
- Fixed crash on graphing y=1/|x|
Reviewing 2.2 (Oct 5, 2012)
Why don't you check Microsoft Mathematics 4.0, it is free and better.
Reviewing 1.76 Beta (Feb 20, 2003)
this is the best graph plotting program i have ever used! it seems to have come back alive... i thought it was dead since last year...
now it's back BIGGER and BETTER!
Highly recommended for school work and education!!
Reviewing 1.75 Beta (Feb 12, 2003)
Wow, haven't used this program in years, I'm amazed it's still alive...
this program helped me through grade 12 Calculus quite a bit.
Anyways, this new version is looking quite spiffy, not too many harsh changes from 1.6 yet, I'm looking forward to 2.0
Also, one thing that always bothered me was the selecting of a graph area and copying it... I'd like it better if it was more scalable, instead of keeping the area 4:3 or whatever it is... also, copy to .png or .jpg would be a nice implementation too, save on some memory space.
