@caveman Why log(2*10^3*6)? Is there a definition for this?

If I want to 3 digit chop pi^2, do I square the true value of pi then chop, or do I multiply 3.14*3.14 then chop?

How is it determined that L = 2 in this example?

How can I show that it doesn't satisfy LC ever? I'm thinking 1 counterexample will not work?

Suppose I want to show that f(t, y) = e^(t - y) satisfies a Lipschitz condition on D = {(t, y): 0 <= t <= 1, -inf < y < inf}.

I want to show |f(t, y1) - f(t, y2)| <= L |y1 - y2|.

Do I just pick arbitrary values for t, y1, y2, and L? E.g. t = 1, y1 = 1, y2 = 0, so

|1 - e| <= L

and I can just say that this satisfies a Lipschitz condition for L = 2?

A function f(t, y) is said to satisfy a Lipschitz condition in the variable y on a set $D \subset \mathbb R^2$ if ... (etc).

Does the $R^2$ mean a two dimensional space of real numbers?

For the language $\{a, b\}^* \{b, aa\} \{a, b\}^*$, is this a correct FA for accepting it?

Is using the pumping lemma to show that a language is not regular the same as using the pumping lemma to show that a language cannot be accepted by an FA?
