Greetings,

Instead of using for(3); you can use for(4):

for ▮, ▮, ▮
▮

The four parameter ｢for(4)｣ gives you the ability to loop while checking a condition. Below is the description of for( {0}, {1}, {2}, {3} )

"For loop. The function of controlled iterations. The cycle repeats {3}, while {0} satisfies the condition {1} and after each passage necessarily satisfied {2}. Repeating expressions can be set to any number of expressions."

example:

for i:=1, i<10, i:=i+2
k:=2*i

Where 'i' starts at 1 and until i is no longer less than 10, perform operation of k:=2*i. Apply operation i:=i+2 and check if less then 10...; LOOP!

May this be of Good Help;

mNewton() from the Maxima plugin is another option. It also may fail for particular initial guess values.
