1)Consider the expression for blackbody radiation given by Equation 4.62 . The integral of this expression over all wavelengths, that is, , gives the total energy radiated by a blackbody per unit area and time. Using Simpson's rule, compute this integral at T=1000K as accurately as possible. The analytical result is given in the literature as , where  is known as the Stehan-Boltzman constant and has a value of 5.67x10^(-8) W/m^2K^4. Compare your numerical result with the analytical value at 1000K. Equation 4.62 is also attached as an image.

2)The RMS value of an electric current I(t), where I varies periodically with time t is given by the expression  where   is the time period for one cycle in the variation of I(t). If I(t) is given as 5e^(-t)sin4pit, with =0.5 seconds, compute the RMS value using Simpson's Rule.
