Hello everybody.
I have this integral:
I used this code:
NIntegrate[
Subscript[\[Lambda], 2][s, u] Vbar[u], {s,
0, T},{u, 0, s}]
How can I put the '2' power?
I tried this code:
NIntegrate[
NIntegrate[Subscript[\[Lambda], 2][s, u] Vbar[u], {u, 0, s}]^2, {s,
0, T}]
This code gives me an answer but it has an error. How can I solve this error?
I attached the code as well.
