limit as x approaches zero
Hi everyone,
I am having difficulties calculating the limit of the following:
\sigma^2}{2|x|\sigma}\right))
with the cumulative standard normal distribution )
and 
being 0.2 or some other constant.
By numerical approximation I have found the following two solutions: 0.5398 for x approaching zero from the left and 0.4602 for x approaching zero from the right. What is strange to me, is that these two values are relatively far apart from each other.
How I can derive the limit of the above in a non-numerical kind of way?
Thanks already.

and 
. In other words, 
has a jump discontinuity at x = 0, so it is not surprising that the composition of this function with a continuous function also has a jump discontinuity.
