Hi,

Suppose I have a function f[x] with singularities or discontinuities at x=b
and x=c.

1. What is the difference between NIntegrate[f[x],{x,a,b,c,d}] and
NIntegrate[f[x],{a,d},Exclusions -> {b,c}]

2. Suppose slist = {b,c}. How do I NIntegrate[f[x],{x,a,b,c,d}]?
NIntegrate[f[x],Flatten[x,a,slist,d]] does not work (as I expected).

Thanks,
Eric
