Hi,

this is my first time to use wxMaxima.

I have a series of equations:

e1 : R10/U10=R2/U20; e2 : R11/U11=R2/U21; e3 : R10+U20=1023; e4 : R11+U21=1023; e5 : R11=R10+epsilon; e6 : R1=(R10+R11)/2; e7 : K=R1/R2;

R2, U10, U11 and epsilon are known

First, I want to solve K

Second, I want to develop the solution in taylor series with respect to epsilon. The error on K is supposed to be of second order of epsilon. This is what I got by hand and what I want to confirm.

Thanks for helping, Olivier
