Right.

This is part of the definition of the function.

How much detergent does she have left?

And then I were to take the partial derivative with respect to y.

Similarly, this is going to be the partial derivative of psi, with respect to y, but when we do the test, we take the partial of it with respect to x so we get that mixed derivative.

And this is should make a little bit of intuition.

Go to hell, Dave.

I don't have to write x and y every time.

Let me draw this, what we're trying to do.

So that equals 0.

Let's call it h of y.

Fair enough.

But our whole goal is just to make this exact.

Do it in this magenta.

That's their greatest common divisor. That's the same thing as 9 2.

Ignore the y there.

large, we can then simplify that get rid of all the, both the angular terms and just have the radial term.

And that's cool, right?

Uh, yeah. Let me get my gear.

Is it 1 or negative 1?

Without that title Romeo, doff thy name And for that name, which is no part of thee,

I won't prove it.

Retrieving My Bugs list...

I want my share!

She was herself again.

They're really mad.

But I think I have a minus 4.

And how do we test that?

It's usually a couple that's having trouble having a child, and they take a bunch of eggs out of the mother.

It's all there?

Your half.

You have to take it.

I'll be back to collect them in 15 minutes.

The lowest value is actually the bottom part of a tower like this.

So, if I take this, you have a minus 4 here.

If you were to take just a partial derivative with respect to x.

It's just the product rule.

So we could essentially say, you know, we don't have to take the integral from t equals 0 to t equals infinity.

Joey, I'm getting tired of picking up your clothes.

Well, what we did is we took all of these individual terms, and these green terms here are just taking the derivative with respect to just x on each of these terms.

Oh, sorry, what if I multiply both sides by 1 2 or another way is dividing both sides by 2.

No, I don't feel like delivery tonight.

He gets his own food and all.

A meeting with himself, so that

So this is derivative.
