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

Now 1 plus 9 is 10, plus 8.

That's just x.

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.

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

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

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

Approximately.

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.

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.

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

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

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

So if we take the partial, with respect to x, of both of these, we know from this that these should be equal, if psi and its partials are continuous over that domain.

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

Anyway, so this is x plus 2 squared.

No remainder.

Because zero times negative four three.

And it's going to be all of that over the old denominator.

Now 225 plus 400 is 625.

So it becomes 4 times 5 to the first power, minus 2 times 5 to the zeroth power.

Let me write it again.

Is equal to the negative square root, the negative square root of x minus 1 squared.

So you could say, oh, it's forty.

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

Then finally the z intercept when x and y are 0 we're on the z axis.

So this is equal to s a times the Laplace transform of sine of a t.

And there we have it.

If this right here is b squared, if the 9 is b squared, right there, then that means that b is equal to 3.

This could be interpreted either way.
