Ch3, The Pattern of human mortality

I m unable to understand the explanation given for the relation
\(q_x\) > mu_x and for \(q_x\) < mu_x
i need a more detailed mathematical explanation for these relations.

Thanks

 

Got this from somewhere. If it can be of any help.

 

And if you want an explanation of the graph, then see this thread-
