I would like to know about the source of the solution provided.

Dirichlet Conditions

It seems to me that Dirichlet conditions and Dirichlet boundary conditions are two different things. The link points to what seems to the wrong one. Am I wrong? KE7KTO (discuss • contribs) 13:38, 7 July 2017 (UTC)

• You are correct they are different, the boundary conditions are equation specific to a particular situation. These boundary conditions are specific to the example chosen. --Marshallsumter (discuss • contribs) 15:09, 7 July 2017 (UTC)

Wrong Solution

In the case with 4 homogeneous boundary conditions it seems to me there is an error in the resolution. In step 3 the equation for the y variable (or equivalently the x one) is reported with a wrong sign and this leads to a different (but I think incorrect) solution. If a remember well one solution is a sine and the other a sinh
