We will continue our talk on ship motions in irregular waves. See, we just spoke about this transformation, that is how do I get encounters spectrum. Now the procedure is straight for us, excuse me simple because what we have to do. See, earlier we had on that for a zero speed H omega against omega and I obtain this response. Say, I call it… but now I have to do the same thing here. I obviously, have to write this H omega e, which also look something like that. And I multiply the corresponding a with corresponding b square, I end up getting procedure is very straight forward. See, earlier I went this way for zero speed case, when there was no speed because this remains same as I viewed and obviously, response also is a function of omega because you would have calculate the responses assuming that there is no motion
