Hey folks.

I need to do a kind of loop calc. in maple and im not shure how to. 

lets say i guess a temperature T.

i then put it through all soughts of eqations where the variabel T is necessary for the outcome of my result, which i then use again as T. the loop should finish when T as a result is the same as my guess in the beginning. like:

T:=45 

bla bla calculation

T_new:= 35

again 

T:=35

bla bla calculation

T_new= 35 

Finish!!

Any ideas?

Hey 

i want to solve these 3 eqations 

21000 = ((10/1000)/60)*4181*983*(x-y)

H = -((10/1000)/60)*4181*ln(1-((x-y)/(x-40)))

H = 124+102'ln(x-40)+(7+2*ln(x-40))

with the result of:

H,x,y

how do i do that?

Thanks
