The Calculus Calculator(CALC) is a programmable, graphing, scientific calculator with the capabilities for integration, differentiation, solution of systems of non-linear equations, complex functions, vectors and lists, and statistical calculations. It is copyrighted by: 630111Novosibirsk-111,box325 Chem.Lab.NCD To try out CC, run the program CC. When the calculator screen shows, press function key F8 (Load:color.cak), select option (C), and enter DEMO.CAK as the file name. Follow the directions that appear on the screen. There is an extensive help facility built into the program (using the file CC.HLP) and a 43 page manual in the file CC3.PRN. To print the manual on your printer, just enter the command COPY CC3.PRN PRN. Updates to the manual are in the file README2.CAK. I welcome communications about CC, especially bug reports and suggestions for improvements. A $25 donation to the Applied Math Fund would be appreciated.
