I just got a FX-CG50. It's a nice calculator but there are some things that just drives me nuts.

I have found solutions to some of the problems but there are some things I can't find any solutions to.

1.

When you get multiple results from an operation, like Pol(3,1), the results are displayed either inline as a list (list/matrix/vector depending on operation) (math mode) or in a list-matrix-vector viewer (linear mode).

To get one of the elements, for example the first, I can run

List Ans

There must be a faster way!

In the list-matrix-vector viewer (or whatever it is called) I can jump between different list elements but I can't find any way to copy the result back to Run-matrix!

For example if I run Pol(3,1) in linear mode and want the length, is there any way for me to copy it directly from the viewer back to the run-matris, ie something like:

Po(2,3 enter

down

enter

instead of having to do something like:

Po(2,3 enter

enter

It would be 8 key presses less !

Is there a solution to the general problem? Ie is there a fast way to copy elements from the list-matrix-vector viewer?

2.

Math mode is nice, but it lacks some functionality that is in linear mode (such as being able to directly enter a graph !? - shift-sketch-graph-y).

However editing in linear mode is not very nice. It is easy to edit the last command (left or right), and it is possible to edit even older commands - ac - up.

No matter what method I use, the screen is cleared and I can't see any earlier results!

Is there a way around this?

Annoyancies

-----------------

Suppose I enter data into two lists in the statistics app.

Then I enter run-matrix and tries to fetch statistics using var-stat-X-x (mean). Now one of two things will happen. Either I will get old results (results that have nothing to do with what I just entered) or I will get an error ("No Data").

After entering the statistics app and running 1-var (or 2-var) I get the correct results.

The best thing would be if var-stat-X-x called the statics app and returned the correct values. If that is not possible the statistics app should at least clear old results when I enter new ones.

This is however not the only irritating thing. If I run 1-var or 2-var statistics in the statistics app, and then do a linear regression the 1-var and 2-var results are lost (the other way around does not work either).

For example:

I start the statistics app and enter data into two lists. Then I run 2-var statistics followed by linear regression. Going back to run-matrix and running var-stat-X-x will result in an error ("No Data").

The other way around will not work either (linear regression first and then 2-var - now the var-stat-graph-a etc will be lost).

Not solved, but without solutions

-------------------------------------------

Copying earlier results in run-matrix!

Solved problems

----------------------

In graph mode if I, for example, search for the intersection of 2 functions, I could not find any way to use the result in run-matrix. However the x and y values (depending on graph mode) is stored in the x and y variables.

In the solver there seemed to be no way to reach the solved variable, but there is. It is just stored in the variable which is reachable from run-matrix.
