What are the questions?
Can you do it later today? Or do you have to do it right now?
Why don't you write back sometime this evening, after 8 or so. That way if I can't help, there will be many other experts online.
I'm pretty busy now.
You can post what you have, but since I haven't seen it I can't guarantee that I'll know it. What exact topic is it going to be about?
Ok, well you can post it.
I'm just worried that if I can't do it, for some reason, that you will be out of luck.
We need more info for #2. Here are the ones I am sure of. Please give me info for #2, and possibly post the other ones in a new thread.

I'd rather not give you the wrong answers, so can you post the others in a new thread?
Oh, I had opted out so that other experts can try to answer these.
There are new questions? Are they going to be similar to these? If so, I might not be able to do them all...
Here are the ones I can help with! I need more info on #2.

Please give me more information about problem #2.
I'm not sure about 8, and I need that figure for #2.
Ok, the area between -1.13 and 2.03 is:
But without seeing the graph, I can't be positive that is what you are looking for.
