Both the integrals are equal to each other. I have used 'nlinfit' to find the equations F(t), from the available input data. x1 is the unknown, and x2 is 1-x1. To try 'fsolve' I need to have it in the form F(x)=0, which is not in ...

Error in MuPAD command: The integrand is invalid. [int] I have tried by defining L as a function of x and t (I am not sure this is really useful) but nothing change. Moreover I also tried: syms t L=@(x) int(CdfGN(t,b),t, -Inf, x); Delta2=integral(@(x)...
Not counting the 4/pi in front, I = Int{0,inf} u(x)*x/(x^2-w^2) dx Use the identity x/(x^2-w^2) = (1/2)*(1/(x-w) + 1/(x+w)) to create sum of four integrals Ia = Int{0,w-eps} (1/2)u(x)/(x-w) dxeps --> 0 ...

As to answering (3.), it all depends on your remembering your calculus enough to be able to integrate a constant times x and a constant times x^2. I think they want this one done by hand. Also you need to know what the definition of "mean value" is.
Precomputation of integrals saves programming efforts, reduces computational burden, and increases the accuracy of solutions. It is of special value in computationally intense applications. MATLAB codes are provided.doi:10.3982/QE329Kenneth L. Judd...
