    Unhappy Please help me derive this value of integral, thanks!

    By the SINE INTEGRAL OF SINE PULSE, we derived in the class that
    pi/2 = integral 0 to infinity ( ( sin w ) / w ) dw

    now PLEASE PROVE that "" integral 0 to infinity ( (sin^2 w ) / w^2 ) dw = pi/2 "" as well.

    I'll be really very thankful as it is very urgent. Thanks
