| **slopfld83.zip** | 1k | 03-08-17 | | **Slope Field** This program calculates a slope field for a given derivative. The slopes can be defined in terms of both y and x. There are also many menus that allow you to customize your slope field. You can set the window and the amount of resolution. It eats up a ton of memory while you're running it, so you may need to either archive things, or set the resolution to "low". This updated version fixes a minor bug and causes the program to run much faster than before. It also provides an opportunity to input a solution to the differential equation and view its graph on the slope field. This is a similar version of my 83+ Slopfld program. However, since the 83 does not support lower case letters and doesn't have as much memory, this version was necessary. |
