Common source amplifier low frequency resonse

    Here's the amplifier in question:

    I'm not understanding this part:

    Why is Cs not included in the current divider ?
    To my understanding of current divider, It = Id+Io, where It is the current flowing through Rd
    So, Io = It*(1/Cs)/(1/Cc2)+RL

    But Cs is in series with Id current. Please explain to me how Cs affects Io.

    Yes, it's correct. I must have gotten confused somewhere but it's fine now
