    first order de - which method?

    My mind has just gone blank - can anyone please tell me the name of the method used to solve this?

    Can't remember what you do when there are two dependent variables..guessing I don't just add a constant of integration?



    Thanks in advance!

    There is only one dependent variable and that is y --- z(t) must be a known function of t


    Since z depends on t simply separate the variables

    dy = z(t)dt

    y = integral (z(t)dt)
