Area Bounded:

Consider the isotherms drawn in the F(E) vs E graph.

Find the area bounded by the isotherm at T=0K and the E-axis.

Notes:
1)'E' means energy.
2)'T' is temperature, 'k' is your Boltzmann constant.
3)F(E) is the equation for the Fermi-Dirac statistics.
4)The above 3 are insignificant for the problem.
