How do i reduce the accuracy...

How do i reduce the accuracy of the results. I am okay if the solution is within 4or5 decimal places. If that doesnt work then i can settle for the last equation(#eq12)(that is difference to be within 2percent). Sir the difference in the HP and HR that is the last equation(eq12) can be within 2percent. If i can apply the command that you used which calculates RHS-LHS for this equation and set it within the limit 2percent i guess the convergance can be achieved for rest of the 11equations. Can this help in converging? Can u please send me the code or please explain me how should i do it? Thanks. Nitesh

in the equation T and Ti are the temperature in Kelvin and hence is grater that zero.

x1,x2,x3... and n are also greater than zero.

if i try to solve Ti from T(input) then the solution is obtained.

this can be done just by changing the input being T instead of Ti and in fsolve command replace T by Ti.

So i guess maple should give me a solution for the reverse which it is not and that is what is required.
