Okay, in this case you've written it in a different order and it makes tons of sense. The way I have it written up there is $${\partial \over\partial x_1} = {\partial R_x\over\partial x_1}{\partial \over\partial R_x} + {\partial r_x\over\partial x_1}{\partial \over\partial r_x}$$ But (and I...

The first part is actually fine. You just note that since r=r1+r2 that means r1=r+r2 and r2=r1-r and you substitute that into the center of mass, R, and simplify to get r1=R+(μ/m1)r, and r2=R-(μ/m2)r But the next part is where I'm very confused. The general idea is that you want to prove ∇1 =...
