I need to solve the system of equations (in Mathematica notation):
r1 == 0.0298
r2 == 0.0335
n == Abs[(r2-r1)/T]
2*Pi*Sum[r1+i*T, {i,0,n}] == 10
T>0
I tried (ignoring T>0) to use NSolve, which didn't work. I guessed the
problem is that the summation limit depends on T which is also a part of the
summand. However, Mathematica succesfully solves the simpler Sum[n, {i, 0,
n}] == 2. What is the essence of the problem? How can I solve it?
