How can I extract a single solution from solving a system of equations, such that I could "automatically" define each variable?

The output is saying too many arguments, but I input 5 for 5 variables.

Help with syntax

I have the CX CAS version and I run Ubuntu 18.04 LTS on a laptop. What are the available resources for writing and testing programs on my computer, and then uploading to my calculator?

Trying to retrieve what is entered in a spreadsheet cell, not the output that is calculated for that entry.

If user defined function contains If statement, it cannot be integrated using nInt(...) command.

I need help to find the solution to this error, i create a spreadsheet with the value of the constants t calculate Cp of the element but I keep getting this error.

I have developed this code on my ti-nspire software. I ported it to Matlab, and it works I'm assuming that there is some simple order of operation errors. Please look it over and see where its wrong desireded function is x^2.10-2sin(x), 0,4,30 the results should be ea=0.000093 xopt=1.427552 As stated this identical code works in mat lab as a function when reformated ideally, I would be able to set the conditions to the while loop as ea>es and have it calculate as many iterations as necessary to get to a reasonable error percentage.
