For the the following equation

\[

u_t = (L + M)u,

\]

where \(L\) and \(M\) are linear time-dependent operators, I am trying to show that the Strang splitting scheme

\[

u_{n + 1} = e^{LH / 2}e^{MH}e^{LH / 2}u_n

\]

has second-order accuracy in time (here \(h\) is the time step).

I am not sure how to do that though.
