So then you get cdc inverse is equal to cc inverse a.

So minus v2 dot v1 over v1 dot v1, times the vector v1, dotted with itself.

Because we're saying 3 times v1, and then, plus 3 times v1.

9 times 8 times 7 times 6 times 5 times 4 times 3 times 2 times 1.

Because I squared, I multiplied the second derivative of y with respect I multiplied it times itself.

After besieging us, they opened fire. This isn't the issue!

What is vi dot v1?

They're that basis vector times your vector x.

This should be 9 times 8 times 7 times 6 times 5 times 4 times 3 times 2 times 1.

So that's times 1, times 2, times 3, times 4, times 5.

To him who struck down the Egyptian firstborn for his loving kindness endures forever

To him that smote Egypt in their firstborn for his mercy endureth for ever

So what is ten times let's just start with zero.

This is the same thing is taking one of their transpose times the other one.

We are left with an x plus 4 times an x minus 3.

And then we have 32 times 31 times 30 times 29 times 28.

So that equals 2 times 5 times 7 times 11.

Heads, tails, heads, tails, heads, heads.

It could be the first four heads heads, heads, heads, heads, tails, tails.

7 times 11 times 10, right?

So we're left with 9 times 8 times 7 times 6 over and this will just be an exercise in simplifying this expression 36 times 35 times 34 times 33.

We're doing it exactly the same way we do a traditional multiplication problem.

So just swap the order that we do this multiplying in.

We have 5 times 4 times 3 times 1 in the denominator.

Five days is 5 times 24 times 60 times 60 again or 432,000 seconds.

It's base times height times 1 2.

7 times 11 times 10 is 770.

So 5 times 8 times 8.

That's 6 factorial over 4 factorial times 6 minus 4 factorial.

It's 0 times this guy plus 1 times this guy. It's 0 times v1 plus 1 times v2. So it's going to be 0, 1.

I'm going to switch colors again, just to stop the monotony.

So, LCM is going to be equal to 33225 180

let me write 2 5 like that so this is the same thing as 3 times 2 times 1 5.

Now, our last row operation we represented with the matrix product S3.

Dotted with v2 dot v1 remember, this green part is just a number over v1 dot v1 times v1.

I end up with? I would end up with 105 times 1,05, it's equal to 110,25.

1 times 2, plus 2 times 1. And then you have 1 times minus 1.

So where do we see multiplication we have a multiplication, a division, a multiplication again.

That equals 4 times 81 times pi.

So it's 5 times 4 times 3.

So v1 dot v2 is equal to 1 3 times 2 3, which is 2 9. Plus 2 3 times 1 3, which is 2 9. Plus 2 3 times the minus 2 3.

Multiplication

So you could view this literally as being equal to 3 times 2 is, of course, 6, so this is the same thing as 6 times 1 5.

4 times 0 is 0, 4 times 0 is 0, 4 times 0 is 0, 4 times 1 is 4.
