Before revision: By doing so finally, two differential equations are obtained which do not depend on each other: Both differential equations have solutions of the form whereat and are constants which need to be determined by using appropriate boundary conditions and is given by .
After revision: which is the inverse of the previously defined transfer lengthBy doing so finally, two differential equations are obtained which do not depend on each other: Both differential equations have solutions of the form whereat and are constants which need to be determined by using appropriate boundary conditions and is given by .
