Explanation / Answer

Everything is correct but you need to put capital 'Vo'in place of 'vo'. Every letter is case sensitive. So type as given in the question.

Derivation is below, you can check

Time constant , T = L/R

current in the circuit, I = Io * (1 - e^(-t/T))

I = (Vo/R) * (1 - e^(-t*R/L))

energy stored in inductor = 0.5 * L *I^2

energy stored in inductor = 0.5 * L * ((Vo/R) * (1 - e^(-t*R/L)))^2

So, the energy stored in inductor is

E = 0.5 * L * ((Vo/R) * (1 - e^(-t*R/L)))^2
