RE: System of non-linear equations
Thanks a lot, it works for that system, but I tried it with my problem and even with an accurate range i cant get my solution :/
my system is:
39.8344274/(y-0.1495645628)-24.52151/(y^2)=
39.8344274/(x-0.1495645628)-24.52151/(x^2)
and
39.8344274/(y-0.1495645628)-24.52151/(y^2)=
39.8344274*ln((x-0.1495645628)/(y-0.1495645628))/(x-y)-24.52151/(x*y)

the solution i am aiming for is x=1.66649546538 and y=0.238068203637, which i can get in graph mode or with the solve app giving an inital guess value like 1.5-0.2, but with fsolve even if i put ranges like 1.665-1.667 and 0.22-0,24 or initial guess 1.5-0.2
I cant get it
