Could you explain me please for WHAT REASON do you post this duplicate problem again ?



==============


By the way, the problem formulation is not correct in your post.


The correct formulation is THIS:


<pre>
    if f = u + iv  is an analytic function and u = Sin(x)*Cosh(y), then find v.
</pre>


It is &nbsp;<U>VERY &nbsp;serious &nbsp;fault</U>, &nbsp;which shows that the person who created this &nbsp;"problem" &nbsp;DOES &nbsp;NOT &nbsp;KNOW &nbsp;the subject.
