This part here to there is what we have done so far, that means, for each frequency I must
find out what is my frequency response, actually why the trough that RAO graph, then
add them up, this become so very simple, this is actually you know, this this is a point
that has to be clear in your mind, because this is not only heave, it this thing will appear
for any response.
Given a wave, find out the response; may be heave, may be roll, may be pressure at a
point, may be bending moment at a point, what we are doing given a wave, what is the it
is given a wave what is the response? Regular wave, I am trying to find out. Irregular
wave is nothing, but sum of regular waves ok.
Each regular wave induces me a response, regular response, add them
