If I recall correctly, you slingshot by entering an orbit with high
gravitational potential energy (GPE), go down the well until you're at
low
GPE (and high velocity), and then burn your fuel before you start
climbing
up the well again.  It's the fact that you had your fuel coming in and
don't
have it going out that makes it work.  I don't recall the math but I'm
sure
someone like Nyrath or Keith W would if you asked prettily.
