Hi, I am new in Maple. If I have an electric network as in the figure, I want to get the Transfer Function V2(s)/Vi(s) from this equation system:

Vi=R1.I1+V1

Vi=R2.I2+V2

I1-I2=C1.dV1/dt

I2=C2.dV2/dt

Which are the commands that I may write to get this?? Before hand, Thanks by your answers!

Hi every one,

I am using Maple 7 because I am running Windows XP

I believe this equation:

 

> solve( 1.15=exp(-xi*Pi/(sqrt(1-xi^2))), xi);

 

has two solutions: xi=+0.4444364945e-1 and xi=-0.4444364945e-1

but Maple only gives -0.4444364945e-1

 

Why?? And how can I get the two solutions?? Thanks before hand by your comments.
