1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

1/√u = u^-1/2 => 2√u not 2u^(3/2)/3

@devout jewel

your limits also transform to be (4-c)→4

[sterile ether]

which as I said becomes 2√u so you get 4-2√(4-c)

which evaluates with the limit to simply 4
