Starting with the symmetrized integrals as in 34, make the substitutions p = 2p/h (where p is the new variable, h is a constant), f(x) = (x), g() = h/2 (p); show that then (x) = 1 h Z (p)e 2ipx/h dp, (p) = 1 h Z (x)e2ipx/h dx, Z |(x)| 2 dx = Z |(p)| 2 dp. This notation is often used in quantum mechanics.
