Joey's Mathematical Calculator Build 8 - Download (444 KB, executable and library file) SciCalc (old, outdated): Joey's Scientific Calculator - Download (132 KB) Your computer requires these library files (1.08 MB) in order to run SciCalc. Simply download the ZIP and extract it to C:\Windows\System\ (System32 for XP users) and click on instructions.txt (Do not overwrite these files if you already have them on your computer!!!)

08/31/2006 - Minor updates to the function grapher interface and the numerical integration interface.
10/7/2005 - Area of triangle using known info ported from SciCalc to MathCalc. Also fixed a bug in MathCalc under the Trigonometry section. Also, my J-function has been implemented into MathCalc just for fun.Usage: Jo(x,y,z,t). For information on what these arguments mean, visit the J-function documentation. 10/6/2005 - Function grapher added to MathCalc! Functionality is more favorable than that of SciCalc. The functions graph much faster and the curves are a lot smoother. Function grapher and numerical calculus form functionality have now been merged together for easy-of-use. Simply type your function in the Function Grapher form and you may operate on that function in either the Numerical Calculus forms to the Function Grapher. Sum() and prod() functions have also been added. Sum() is the equivalent of sigma notation (summing) and prod() is the equivalent of pi notation (product). Documentation for usage of these two functions is as follows:6! (6-factorial, 1*2*3*4*5*6) = prod(n,1,6,1,n) The first appearance of 'n' declares which variable will be doing the iterating. The 1 (before the 6) represents where n should start in the sequence. The 6 indicates where the n ends. The 1 (after the 6) represents how many times n should increment itself after an iteration. The 2nd occurence of 'n' represents the expression getting evaluated for each term of the product. The sum() function behaves the same way; that is, the notation is exactly the same. Examples: sum(t,1,7,2,t) = 1+3+5+7 sin(x) (to 20 summation terms) = sum(k,1,20,1,(-1)^(k+1)*x^(2*k-1)/prod(n,1,2*k-1,1,n)) 10/2/2005 - Numerical calculus updates among a couple geometry updates.
9/15/2005 - Law of Cosines added to the trigonometry submenu and numerical calculus functionality added.
9/14/2005 - A couple of geometric and trigonometric menu items have been ported to MathCalc from SciCalc. The code has been updated to run more efficiently and the user interface has also been updated to the new format. Progress on my work will continue.
9/7/2005 - MathCalc has finally been released! Functionality is limited but some of the functionality from SciCalc has been ported to the new format. PLEASE e-mail me if you have any problems. Bug reports, bad calculation reports, etc. let me know. There DEFINITELY WILL BE updates to MathCalc in the future so keep a lookout!
7/27/2005 - It's been nearly a year since the last Scientific Calculator release but now I am working on a different project. It's still the same old Joey_21's Scientific Calculator with a new color twist! I am renaming the project to Joey_21's Mathematical Calculator for these newer versions. The whole entire calculator project is started off with fresh code in this upcoming project. Features are still in the process of being ported from the old "Scientific Calculator" into the "Mathematical Calculator". The "Scientific Calculator" project will remain available, however, it will no longer receive updates. All future versions of the calculator will be released under Joey_21's Mathematical Calculator. Over the past few days, I have been in the process of creating my own expression and function parser to make the code and computing more efficient. Hopefully this will enable me to get rid of a few of the required OCX files under the current Scientific Calculator.
