How does the Compton effect wavelength formula work?

[bcphysicist]

Can somebody please explain the Compton effect to me... I don't get how Compton came up with the wavelength after scattering - the initial wavelength = h/the mass of the electron*the speed of light*(1-cosine of the scattering angle). Thank you!
