  • The image displays a horizontal line segment, suggesting a one-dimensional spatial domain.
  • An arrow drawn above the line indicates the variable \(x\), pointing from left to right, suggesting the direction of the coordinate system.
  • The bottom edge of the line segment is labeled with \(0\) at the left end and \(l\) at the right end, defining the spatial interval \([0, l]\).
  • The side labels indicate the left boundary as \(u_L\) and the right boundary as \(u_R\), representing boundary values.
