HP4950G Solving by root or SYSEVAL
I have the following program
on the HP50G : P0 \\<< NOVAL \\> p A \\<< 'p\\.S(A,A,e^X^2.,X)/\\v/\\pi' 'A' 2. # 2F12Ch SYSEVAL 'IERR' PURGE \\>> \\>> Or « NOVAL p A « 'p(A,A,e^X^2.,X)/' 'A' 2. # 2F12Ch SYSEVAL 'IERR' PURGE » I introduce a p value and find the A value by the solver. Instead of ROOT, I use # 2F12Ch SYSEVAL, in order not to have to create and delete the unknown variable /value A. But a 'iERF' variable is created to evaluate the accuracy. How should I proceed for not having appear that 'iERF'? Another question: Suppose the function to be integrated and solved is almost all written in RPN mode: \<< .8 0. \> p A \<< \<< p A NEG DUP NEG 'e^X^2.' \pi \v/ \>NUM / X \.S \>> 'A' 2. # 2F12Ch SYSEVAL \>> \>> What is here to be corrected? If easier, suppose I use the ROOT command and not # 2F12Ch SYSEVAL? Thanks for your help.
