Find a monic polynomial p(x)=x^n+...of degree n with the least integral

∫p^2(x)dx on [-1;1]and find he minimal value of that integral

the same for ∫p^2(x)exp{-x^2}dx on (-∞;∞ )

let Kr:[-π:π]->R+
be non negative continuous function such that Kr(-π)=Kr(π)
1/(2π) ∫Kr(s)ds=1( integral on [-π:π])
and for any l>0
limKr(x)=0 when r->∞
uniformly for |x|≥l.let f be a 2 π-periodic continuous function.Show that f*Kr->f for
r->∞ uniformaly with respect to x in [-π:π]
