Figure 19.3.2: \mathop{R_{C}\/}\nolimits\!\left(x,1\right) and the Cauchy principal value of \mathop{R_{C}\/}\nolimits\!\left(x,-1\right) for 0\leq x\leq 5. Both functions are asymptotic to \mathop{\ln\/}\nolimits\!\left(4x\right)/\sqrt{4x} as x\to\infty; see (19.2.19) and (19.2.20). Note that \mathop{R_{C}\/}\nolimits\!\left(x,\pm y\right)=y^{{-1/2}}\mathop{R_{C}\/}%
\nolimits\!\left(x/y,\pm 1\right), y>0.
