Don't you need the integral of sin^2(x)/x^2
which according to

http://www.sosmath.com/tables/integral/integ37/integ37.html

is pi/2 from 0 to infinity

Is integral # 12 from that table correct ? Shouldn't it be cos^2 instead of cos ?

because sin^2(x)+cos^2(x) = 1 (locus of a circle),

yes - well spotted
