A:
Preview: ... r changing the variables you get the integral 2/pi int from 0 to infinity of f(ut)/(1+t^2)dt Now, f(ut)/(1+t^2) goes uniformly to f(0)/(1+t^2) since f is bounded, therefore the integral goes to 2/pi int form 0 to infinity of f(0)/(1+t^2)=f(0)*2/pi*int from 0 to infinity of 1/(1+t^2) =f(0) since int from 0 to infinity of 1/(1+t^2) =pi/2 (here we use the fact that an antiderivative of 1/(1+t^2) is arctan(t) second circled problem: Denote F(x)= int from 0 to inf of e^(-u^2)cos(xu)du ...
