A function I wrote for the TI-92 to find a particular solution for an ODE (in plain text format).
*Note: TI-92+ functions/programs (except some C/ASM programs) can be sent unmodified to the TI-89. TI-92 programs/functions may need to be modified to run on the TI-89/92+. To "unzip" the downloaded files, you will need an unzipping utility such as Winzip; after this, use TI Connect to send the files to your calculator.
**This program has been written in C. Currently, the TI AMS does not allow using C programs in expressions (e.g. mycprgm(5)+2->myvar).
There is a patch called IPR that overcomes this serious limitation, but be sure to install Kevin Kofler's h220xtsr if you have a HW2 calculator.
"The task is not so much to see what no one has yet seen, but rather to think what no one has yet thought, about that which everyone sees." --- Erwin Schrödinger.
"Everything that the human race has done and thought is concerned with the satisfaction of deeply felt needs and the assuagement of pain... feeling and longing are the motive force behind all human endeavour and human creation." --- Albert Einstein.
"I am satisfied with the mystery of life's eternity and with a knowledge, a sense, of the marvelous structure of existence -- as well as the humble attempt to understand even a tiny portion of the Reason that manifests itself in Nature." --- Albert Einstein.
"Science has brought forth [the danger of nuclear weapons], but the real problem is in the minds and hearts of men." --- Albert Einstein.
"We have developed speed but we have shut ourselves in. Machinery that gives abundance has left us in want. Our knowledge has made us cynical, our cleverness hard and unkind. We think too much and feel too little. More than machinery, we need humanity. More than cleverness, we need kindness and gentleness. Without these qualities, life will be violent and all will be lost." --- Charles Chaplin, speech from 'The Great Dictator'.
