Hello, i am trying to solve the following equation shown bellow, by solution i mean to find all the combinations of R2 and Vs2 that solve this equation. i tried with simbolic matlab as shown bellow.

How it could be done with matlab?

Thanks

syms L R t Vr Vs Vs2 R2

L=1

R=1

t=1

Vr=1

Vs=2

Eq1 =0== Vs*(1-exp((-R*t)/L))-Vs*(1-exp((-R*t)/L));

t_sol = solve(Eq1, t)

Is there a typo in the formula? Should it be

Eq1 =0== Vr*(1-exp((-R*t)/L))-Vs*(1-exp((-R*t)/L));

If not then the equation makes no sense to me.

it means solving eq1=0;

i am not sure if the method is correct
