[en] The solution of the two-dimensional Laplace equation satisfying Neumann boundary conditions on a semi-infinite boundary is obtained using the Fourier Cosine and Sine transforms. The case of a flexible plate in uniform flow is considered in detail and it is shown that the expression for the velocity potential for plates with fixed ends is a special case of that for cantilever plates.
