fsolve() crash with given Interval

I am sure the designers thought of the wish to pass any cas object to the apps. Working inside the apps is ok for demonstration purposes and for doing exercises, but when using the device in practice you soon get to a point where expressions not only depend on x and y.
There is much I criticise, but about this I cannot believe the things did not come up.


Would it be an Option that in the apps each equation uses variables like x any y but they can be changed in the dialog or by the plot commands?

Using my emulator the indices and the calling mechanism is modified by the calc. You don't Even See the 1 based index in the History in the above example.
