RE: Solver Giving Nothing
The CAS solver works with exact coefficients, since you have approx coefficients it will try to convert them to exact coefficients, and this fails because 127e12 is small and is converted to 0. The solution is to write exact coefficients yourself:
Code: s:=solve([127*10^12=(a*b)/(a+b) , 8377*10^3=((a+b)/b)^2],[a,b]) Code: evalf(s)
