Sorry for the long delay between versions, but here is graphDS v0.8! I think that you'll find it worth the wait. I made some pretty substantial additions, so please download. ;)
Additions/changes:
-Two new graph modes: slope field and Euler's method.
-Added a CAS to simplify algebraic expressions, including foiling
-Increased calculation and graphing speed by 2.5x
-Made function nIntegrate faster and more accurate
-Added new catalog functions for approximating definite integrals: euler, monteCarlo, simpson, trapezoid

You can find more info at my site (http://robertson.heliohost.org). If you like graphDS and want to help me pay for college, you can make a donation (https://www.paypal.com/us/cgi-bin/webscr?cmd=_flow&SESSION=f6FsCLPotYIwl3EmMCOYbaee94mzHEQxsg2uahLAFB QRus2FafGMY1GEHe0&dispatch=5885d80a13c0db1f1ff80d546411d7f84f1036d8f 209d3d1d9c4945337c357ab). :)
Edit: I wrote the CAS from scratch myself, so please tell me if you find any bugs (but please read the readme before using the CAS).
