(E)=41R2=h2L2(2mE) The expression (4.39) for (E) is valid only for large E because the area of a quadrant of a circle overestimates the number of lattice points nx,ny inside a circle of radius R. Use Program IdealGasNumber0fStates to explore how the relation =R2/4 approximates the actual number of microstates. The program computes the number of nonzero, positive integers that satisfy the condition nx2+ny2R2. What is the minimum value of R for which the difference between the asymptotic relation and the exact number is less than 1%
