Unknown Well,it is not a great function drawing tool,it can only draw a function that contains "xxx...(10)" at most，x**-1 at least But i am still interested in developing it There are many powerful function drawing tools,but isn't it happy to learn and develop,try to make it by ourselves And there are 2 files,the one named "include1" is more powerful,the one named "FGUI" is older,but on the other hand it is stabler
