 ## Introduction
 
-In this example we will discuss Hamiltonians with a periodic time-dependence and how we can solve the time evolution of the system in QuTiP.
+In this example we will discuss Hamiltonians with periodic time-dependence and how we can solve the time evolution of the system in QuTiP.
 A natural approach to this is using the Floquet theorem [\[1, 2\]](#References).
 Similar to the Bloch theorem (for spatial periodicity), this method helps to drastically simplify the problem.
 Let $H$ be a time-dependent and periodic Hamiltonian with period $T$, such that
