  • Latest Changes

    - 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

    Why don't you check Microsoft Mathematics 4.0, it is free and better.

    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.
