The density of electron states in one, two and three dimension is evaluated by following a simple procedure which makes the significance of Fourier space apparent. Using this approach, the relativistic electron gas is also discussed. The approach is easily adaptable to an undergraduate physics course. PACS numbers :,81.05.BX, Key words : Electron gas; Density of states; Relativistic electron gas.
