A single click on a file will select and focus, a double click opens the file or steps into the directory.

You then run take to take out the sub matrix.

We can do that with one return statement.

Maybe we test it out on a bunch of inputs.

When you run naive(a, b) does it return whichever of a or b is the larger one?

All right, next we have a bit of a trick question I'm importing the regular expression library and then I'm calling re.findall on the regular expression a z

Please select revision A or revisions A and B first.

I'll call it b note outstanding.

So can we somehow pattern match this to that?

So here's my matrix of A.

So, here's a matrix

It's going to be the integral, let's just say from t is equal to a, to t is equal to b.

And let me do something else.

Here's the idea If

This is the same as A A because anything times 1 is just itself.

A is unchanged because there's no rewrite rule in our grammar for dealing with it, but a exp becomes a expression expression, a expression expression, a open expression close, and a num.

So maybe we'll have a is equal to ...

And the A could be for Arcade

3t plus some number.

If it has a Eulerian path, notice what has to happen to all the nodes along the path.

B and I've set C to be equal to AB.

Let's make a greater than 0.

And it turns out if that you are computing A times A inverse, it turns out if you compute A inverse times

Those are pretty intuitive, I think.

What does that tell us?

Now let's do something interesting.

That becomes this first column of this transpose.

In the second question we apply total probability.

I can't remove this line because we actually need to return A to have the same value.

Now, the big insight you need to have whenever you have an absolute value equation like this is to remember, if I have the absolute value of a is equal to 11 what do we know about a?

I said that, because I need a lot of space for what I plan to do.

Well, phi is equal to A over B, which is equal to A plus B over A we know that A plus B over A is the same thing as

It looks something like that.

So I can take the second column of

Think of it as basically the inverse of A and that's the inverse of A and second set, you know, 10 equals p of A and of temp times

Does it calculate a b, or for that matter, does it calculate b a?

We're going to reserve a proof for it for an algebra class that you might take in college or in high school.

Well, here we have two numbers that add up let's say that a is equal to fj.

So we could get any point on this line right there.

Simmer down

Then we want the result to be the value of a that's the bigger one.

So this was the situation.

We can imagine framing this as some hypothetical procedure optimization okay.

But what if we reframed Ehrlich further?

Maybe there was a third constraint that a is equal to 1, or b is equal to something else, or a plus b is equal to something else.
