Abstract Let us consider d 2 y d x 2 + y = Q ( x , a ) , y ( 0 ) = y ( 1 ) = 0 , x , a ∈ ( 0 , 1 ) . . In the following paper, various differential equations will be displayed, which willbe solved using Galerkin’s numericla method and where formal solutions and their numerical approximations can be seen with GeoGebra animated Apptles.
