Uniformly Valid Solutions of Laplace Equation 
IV.2 The vicinity of a sharp trailing edge 
The new problem that we investigate now is formulated as 
follows : 
~ sash = ~ ~ 
B = x(s) +e(co(s) * egs)) te“ $(s,¥,Z,€ )

We must solve :

with the matching condition at infinity. 
It is easy to see that the 2 ie

We did not prove the expected result :
