comment Finding $G'(2)$ when $G(x) = \int_0^x h(t) \ dt$
I have rolled back the post to the prior version. It is best to let the post stay, in case anyone else has this question or one like it in the future.

comment Lift-club rates (This should be really easy)
Now, if you pay Joe \$2 per trip instead, then the following situation applies: you lose \$0.67, Joe gains \$0.67, and Bob gains/loses nothing. This is advantageous to Joe. If they split that extra money, then they each gain \$0.33 whilst screwing you over. Nevertheless, this is less of a gain than if they don't screw you over.

comment Is there a difference between tipping and toppling
Belongs on engineering.stackexchange.com. More generally, as with any term or phrase, we must explore how it is defined. Are they defined differently? In mathematics, these are not common terms.
