Hi,

Im trying to evaluate a Transfer function from a block diagram.

i have written all the equations but i cant find the command to find the symbolic solution

of theta_l/Theta_d in terms of A,B,C,s,Kp,Kv

attched is the maple file.

i use maple 13.

hi im trying to do a pretty simple 2 eq system

and i get

> e1 := 1.74*10^(-15) = D*exp(-Q/(8.31*1473));

> e2 := 7.1*10^(-15) = D*exp(-Q/(8.31*1573));

> solve({e1, e2}, {D, Q});
Warning, solutions may have been lost
 

any help will be appreciated
