Yes, the exponential forms don't e-mail very well.  E[...] is intended to 
be E^[...] or, equivalently, Exp[...].
I thought the differentiation in the other part of this example was strange.
The user wanted to differentiate with respect to b, but the dot-product
notation suggests that b is a vector, and then differentiation makes no
sense.  The answers obtained appear to assume that b is a number after all.
But then the notation is peculiar to say the least.
