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 my case. ...
ans = int((x*cos(x)*sin(x))/(a^2*cos(x)^2 + b^2*sin(x)^2)^2, x, 0, pi/2) >> pretty(ans) pi -- 2 / | x cos(x) sin(x) | --- dx / 2 2 2 2 2 0 (a cos(x) + b sin(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.
Integral bounds only apply todefinite integrals. If you have acontinuous function(i.e. one that extends towards infinity), you must put bounds on the function in order to integrate it. When you place these lower and upper bounds, it becomes adefinite integral. An integral without bounds is ...

In the case of normally distributed shocks, the integrals can be constructed in a closed form. After the integrals are precomputed, we can solve stochastic models as if they were deterministic. We illustrate this technique using oneand multi゛gent growth models with continuous﹕tate shocks (and ...
