Modern units might have a coefficient of performance of approximately 3 (i.e., 1 kW of electricity will produce 3 kW of cooling).

Coefficient.

Real coefficient

Imaginary coefficient

leading coefficient.

And notice this coefficient is the same as that coefficient.

The leading coefficient of the first row is 1 2 is the leading coefficient of the second row 4 is the leading coefficient of the third row, and the last row does not have a leading coefficient.

By the inverse of the coefficient.

As an example, assume that inside the closed system a 100 W heating element is activated, and the air conditioner has an coefficient of performance of 200 .

3 The Gini coefficient (coefficient of income concentration) makes it possible to numerically assess the degree of inequality.

China s coefficient is 0.47.

Target values Gini coefficient

That's the fifth coefficient.

What's the sixth coefficient?

This coefficient becomes 4.

The coefficient is 1.

So what's 1 2 of this coefficient?

So the coefficient of friction tells us

And remember coefficient of friction are unitless

In the next few videos, we'll use coefficient of friction or calculate coefficient of friction to do some more problems

These are the same surfaces is why should the coefficient of friction here why should the coefficient of static friction so this is here, this is stationary what's under place of coefficient of static friction why should that be larger than the coefficient of kinetic friction over here?

You literally just look at this coefficient right here, and you say, OK, well what's half of that coefficient?

If we can't get a 1 coefficient, we'll at least have a lower coefficient here.

Times its coefficient times the fifth term's coefficient divided by 5, for the fifth term.

I'll do a video on why sometimes a coefficient of static friction can be different than the coefficient of kinetic friction

So we can say this generally coefficient of kinetic friction is less than or equal to the coefficient of static friction

The first coefficient is 1.

So, the coefficient is 1.

The coefficient here is 1.

We determined the undetermined coefficient.

The coefficient here is 11.

The coefficient there is 1.

The coefficient there is 2.

Well, half of that coefficient is negative 2.

We call this the coefficient of static friction

And the interesting thing here is that the coefficient the way I've set up this problem the coefficient of kinetic friction is lower, if we assume the same materials than the coefficient of static friction

And the worldwide Gini coefficient of inter country inequality fell from 0.653 to 0.556 from 1980 to 2007, owing largely to the astounding performance of the emerging countries, particularly China and India.

4A plus C, the coefficient of the s terms.

Plus B, some undetermined coefficient times cosine of x.

you could figure out this coefficient of kinetic friction

Pass the first coefficient down 3.

That becomes the new coefficient, right.

that is, what's the coefficient matrix?

I could just create a coefficient matrix, where the coefficient matrix would just be, let me write it neatly, the coefficient matrix would just be the coefficients on the left hand side of these linear equations.

The leading coefficient here, the coefficient on the highest degree term in standard form it's already in standard form
