I have built a simple expression where we can see that its solution t-Vs=1
for some reason the only solution it gives me is t=1 Vs=0
but there could be much more solutions,how can i see more solution combinations?
Thanks.
syms L t Vs
Eq1 = 0 == (1-exp((1-t-Vs)/L));
t_sol = solve(Eq1, [t Vs])

Ask to solve for one of the two variables, which will give an expression in terms of the other variable.
When you solve for more variables than you have equations, often it will say there is no solution. Sometimes it will use internal initial values that you have no control over.
