 Author Comment/Response Michael Woodhouse 07/26/12 08:22am After taking some limits I get a lot of terms of Interval[{0,0}], which I want to set to exactly zero so that they will all cancel out. So Far I haven't found a method to do this, I'm hoping that this is a simple case of not knowing the correct command. Thanks, Michael Here is an example output if it helps...
