Sentences with phrase «about systems of equations»

This observation led to a discussion about systems of equations that could actually be solved more quickly, more accurately, and with more understanding using substitution rather than with matrices on the calculator (e.g., the system of equations y = 3x and y = x + 3).

The teachers felt that some students involved in lesson 1 were not capable of more advanced reasoning about systems of equations and also felt that students could succeed on the state test by following a sequence of steps on the calculator without thinking much about them.

However, by not doing so in the given lesson, it seemed likely that they missed out on a teachable moment to help students reconcile the calculator output with their existing knowledge about systems of equations.

Through surveys and other analysis, they identified a long list of factors that were interacting like a chemical equation, which is the unsexy secret about how education systems usually work.

Using a pair of governing equations that assume swarmalators are free to move about, along with numerical simulations, the group found that a swarmalator system settles into one of five states:

For example, the first inference drawn about teachers» knowledge in this paper might motivate the formation of items that measure teachers» knowledge of using the graphing calculator to facilitate the exploration of multiple representations and solution strategies for systems of equations.

Whatever is known about the properties of spatio - temporal chaos in the solutions of some systems of partial differential equations is not going to invalidate conservation laws or lead to rapid fluctuations in the energy content of the earth system.

That we even try to predict a system as complex as the natural world with a bunch of equations is, to me at least, the perfect example of the hopeless search for an explanation which is everything that science should be about.

Now the claims I make are: 1) The equations are independent and the system of random symbols has a unique solution 2) This solution uniquely determines the velocity, pressure and density fields in the steady 2 D case 3) If one of the 2 fluids condenses then I obtain the dependences of the fields on the condensation dynamics (rate, spatial distribution etc) what is actually what this whole thread is about.

Namely that the first law of thermodynamics, being an equation of equilibrium thermodynamics, can not give information about the dynamics of the system.

Everybody agrees that if there were no feedbacks in the climate system, then the resulting climate sensitivity, as dictated by the S - B Equation (using the effect radiating temperature of 255 K for the earth) is about 0.3 C per (W / m ^ 2).

The role of stochastics is then even more crucial: (a) to infer dynamics (laws) from past data; (b) to formulate the system equations; (c) to estimate the involved parameters; and (d) to test any hypothesis about the dynamics.

Climate models are, at heart, giant bundles of equations — mathematical representations of everything we've learned about the climate system.

Imagine including the next nearest star system in your equations — the Centauri system, which has three components that we know about with a combined mass more than twice that of our sun.
