So, this is obviously telling us that mu of x is equal to x.

That's 5P 3, and we want to set that equal to 3 4 P.

What is that?

So it's 1, 2, 3.

Now 1 plus 9 is 10, plus 8.

That's just x.

like things are going to work out. So we could select a is equal to positive 5 and b is equal to 3. Those would work out to ab equal 15.

So if you subtract the big part minus the little part

So this distance right here, the length of the rope, is equal to 25 feet.

That was my definition of vector addition.

So, 5_5 _ _ _ is going to be equivalent to just 55.

We want to find a times b that is equal to 1 times 6, which is equal to 6.

Notice it's at negative 4, right above A.

You'll have to also subtract 11 from the 7.

And let me just draw some points here, so it's 1, 2, 3

So let me do that in I want to do that in a different color.

You could just swap these two the partial of P with respect to y minus the partial of Q with respect to x da.

So you could say that this is equal to x plus 5 over x minus 2.

Now this is the trick here.

Non zero number.

Then this is going to be equal to zero.

Which is going to be a positive.

So this is 3 times 0.

So if you, if you, the 3 would replace the x. So, f (3), so f (3) is equal to 3 plus 2, which equals 5, right?

So the decimal will end up right over here.

7 plus 44 would be 51, so this is going to be 61.

Well the next one is easy, it's already in decimal form.

If we go down here, 8 plus 5 is 13.

So we get vf squared is equal to 2 times force times distance.

Minus 3.

So if I do 2x plus x plus 3x that's going to equal 120 feet.

And that's x squared plus ten x plus twenty five.

But we see here, just by looking at these two, they don't equal each other.

No, they just...

One times zero.

And the partial derivative of psi, with respect to y, is equal to N.

Let's have 3 groups of 3.

Well let's take the partial of psi with respect to y.

Divide both sides by 2.

I think you get it now

And then that is equal to the right hand side of the equation.

All right, the coefficient in front of the x squared term is equal to a 1.

It's eleven plus eleven or we could've added two to itself eleven times, but that is equal to twenty two.
