Twist!

Twist.

After tightening the level screw lock nuts, verify with one more pass along the Z axis that there is still no twist in the machine

You must twist it right, then twist it left.

Oliver Twist

Oliver Twist.

Twist them.

Le twist.

1, 1, z, z looks like this z would look like, z would look like that.

Come on, twist me around your little finger. Come on, twist.

The clodhopper twist.

Z squared minus 4 is z plus 2 times z minus 2.

(t time z 2 minus z 1). Is this equal to the argument of (z 2 minus z 1)?

So if a is z, so it's z plus 2 times z minus 2.

I'm gonna twist ya.

It's called a twist.

Oliver. Oliver Twist, sir.

You mean young Twist?

The young Oliver Twist.

Where is Oliver Twist?

Brady can twist things...

It's z plus 2 times z minus 2.

So times z plus 1, times z plus 1.

So it's z plus 4 times z minus 2.

And, let's draw the vectored Z 2 minus Z 1 so let's say that this here is the vector and lets draw the vector Z 2 minus Z 1 now what would T times Z 2 minus Z 1 look like?

But there is a twist.

Did you twist your legs ?

Did you really twist it?

Give 'em a twist. Yeah.

They'll twist what I've said.

I'll try to twist it.

That's the lousiest full twist...

Bert didn't twist any minds.

As I do the twist

(t 1) times (z 2 minus z 1) is going to look like this. This is (t minus 1) times (z 2 minus z 1).

This is (t times z 2 minus z 1) and the green one, just to be clear is (z 2 minus z 1) is that.

Rotation Z

Z rotation

z rotation

z rotation

So what is z sub one times z sub two?

And let's see, this z cancels out with this z.

So this is equal to 7z times z plus 1, times z plus 2, times z minus 6.

That choice B, the argument of z z 1 is equal to the argument of z z 2. Now lets think about this a little bit.

This right here would be T times Z 2 minus Z 1. Now what would T minus 1 times Z 2 minus Z 1 look like?
