Featuring the iPhone's new "push notification" technology and one-click donating, changing the world just got easier.     Find out how changing the world just got easier  >

f(x) = (integral)(0-inf) ( a(y) cos yx + b(y) sin yx ) dy


    a(y) = 1/PI (integral)(-inf-&gtinf) f(t) cos ty dt


    b(y) = 1/PI (integral)(-inf-&gtinf) f(t) sin ty dt


f(x) = 1/PI (integral)(0-inf) dy (integral)(-inf-&thinf)f(t) cos (y(x-t)) dt
