(n, l, hw)
return (2*n + l + Rational(3, 2))*hw
Returns the Energy of an isotropic harmonic oscillator

    ``n``
        the "nodal" quantum number
    ``l``
        the orbital angular momentum
    ``hw``
        the harmonic oscillator parameter.

    The unit of the returned value matches the unit of hw, since the energy is
    calculated as:

        E_nl = (2*n + l + 3/2)*hw

    Examples
    ========

    >>> from sympy.physics.sho import E_nl
    >>> from sympy import symbols
    >>> x, y, z = symbols('x, y, z')
    >>> E_nl(x, y, z)
    z*(2*x + y + 3/2)
