Spreadsheet: I can't use solve()
Thanks for read and sorry i'm not good speaking english.I trying to use solve() writing on cells and program but don't give me the answer. Example:
When i write =solve( B+34=0,B) give me {B} When i write =rp(A1,A2,A3) give me {B} EXPORT rp(A,C,D) BEGIN LOCAL E1; 200/(('B'A)*(C*'B'A))=D▶E1; RETURN solve(E1,'B'); END; What i can do ? When i change RETURN solve(E1,'B') to RETURN E1. Hp write the equation whith the numeric valors.For that i think i use wrong solve().

RE: Spreadsheet: I can't use solve()
Hello,
In the spreadsheet, A1 cell, type: =solve(B+34=0, B) BUT BEFORE YOU PRESS ENTER, click/select on the CAS menu (so that the cell is evaluated using the CAS). You should get {34} as the cell value (the cas solve function returns the result in a list because it can solve for more than 1 variable at once). You can also type: =Solve.SOLVE(B+34=0,B) (AND MAKE SURE THAT CAS IS NOT CHECKED) to use the SOLVE function from the Solve app. This will return 34 for the cell Hope this helps Although I work for the HP calculator group, the views and opinions I post here are my own. I do not speak for HP.
