Subject:   complex line integration

ok, i have two lines m and n  ,m is horizontal and n is at an acute angle to the
x axis. I have this function

called R where R is the distance between any two points on the lines. so R =
now i have to perform double integrals the first over the length of n where
dln=dxn+dyn since it is angled.

so first i have to integrate 1/R over dln

to integrate 1/R over dln, this doesnt work out becuase there remains unknowns
like yn when first

integrated wrt xn and xn when integrated wrt yn

i dont require a closed form solution since the double integral will be
evaluated numerically using the lobatto
