Hello

I need to solve the following equation:

Arg[-(I/((1+I \[Omega])^2 \[Omega]))]==-\[Pi]

I have tried Solve (empty output), Reduce (it gives some results but not 
the answer Omega=1) and FindRoot (it gives Omega=1 but it is a 
numerical search).   Is there a way to get the solution not using a 
numerical search?

Many thanks

Ed

PS.   I need to solve several equation of the same kind.
