Well, let us assume at each step the original line is broken into fragments of equal length. After the first step we have 4 fragments of length 1/4, after the second we have 16 fragments of length 1/16, etc. Then we have

Hence

I think you mean dy/dt in the second equation. If you divide the second by the first you should get

eliminating the parameter t.

There seems to be some confusion here. What Whizzies means is that (excluding complex numbers) log(y) is only defined for y > 0. The problem involves log(x+3), so y = x+3. It is fine for x = −1; it is the y that needs to be > 0.

That was what I thought as well until I found this:

That might be the maximum but I don’t know how prove it yet (with or without Langrangian multipliers).

Well, they’re not that difficult.

#1. What is CD in Roman numerals?

#2. The cube of a number is that number multiplied by itself three times – true or false?

#3. What is the pseudonym of the writer Mark Twain?

Perhaps those students of Harvard, Princeton and MIT would also be interested in the following questions?

This step

is not valid. Epsilon might be less than or equal to 2.

I don’t really know how you could go about choosing a suitable N for this problem. Let me think about it.

So instead of x' you have to type x^{\prime}?
