3. ## How can you weigh a living fish?

Yes, that's exactly right. With a few notes...

I think you've got it now. Glad you enjoyed it.
7. ## Can you find a closed form equation for the sequence?

I'm assuming you can't use floor or mod?

9. ## Limit derivation

Sorry messed up the OP. lim(1-(1-1/x)^x) [x→ ∞] = (1-1/e) or lim((1-1/x)^x) [x→ ∞] = 1/e The main question of how it is derived stlil stands.
10. ## Limit derivation

lim((1-1/x)^x) [x→ ∞] = (1-1/e) How would one derive this limit?
11. ## Mnemonic

My bad. I got them mixed up. I guess both are B then.

14. ## Mnemonic

floor(x + 1) is more easily written as ceil(x)
