Hi everyone,
my unknown parameters are D and nR, I want Rg will be less than 0.5
How is it possible?
p=100;
pi=3.14;
asec=0.2179;
k1=1.3663;
Lg=35;
Wg=32;
k2=5.6641;
Lr=3;
b=0.01;
R1=((p/(pi*Lc))*(log((2*Lc)/asec)+((k1*Lc)/sqrt(Lg*Wg))-k2));
R2=((p/(2*pi*nR*Lr))*(log((4*Lr)/b)-1+((2*k1*Lr)/(sqrt(Lg*Wg)))*(((sqrt(nR)- 1))^2)));
Rm= ((p/(pi*Lc))*(log((2*Lc)/Lr)+((k1*Lc)/sqrt(Lg*Wg))-k2+1));
Rg=((R1*R2)-(Rm^2))/((R1+R2)-(2*Rm));
Thank you.

I see no unknown variable ‘D’ here. Also the variable ‘Lc’ is not defined. Do you mean that Lc and nR are actually the two unknowns? Also you need to specifically define ‘Rg’.
This looks as though it calls for ‘fsolve’:
