The New Quick Graph
We left all of the functionality from the previous version free, but there are some changes to the interface that you need to be aware of. We did these changes to enhance Quick Graph capabilities.
The major change is that we removed the z=|y=|x= buttons and now you have to type these variables explicitly. For example, if before you selected z= and you entered the expression x^2+y^2, now you need to type z=x^2+y^2 to get the same result. Why did we do this? because Quick Graph is capable of much more now, so if you upgrade to the new “enhanced” version you will be able to graph expressions like z^2=x^2+y^2. This kind of expressions are called implicit equations, they allow you to make amazing graphs with Quick Graph!
Another change is that we removed the “Cartesian, Spherical, Cylindrical, Evaluate” buttons, but the functionality is all still there. You can type whatever expression you want and now Quick Graph will detect the type of coordinate system automatically.
Feel free to write us any suggestions or questions you may have with the new version of Quick Graph.
