МАТЕМАТИКА за ВСЕКИ cgi-bin Matrix Solver Solving a linear equation system of up to 20 unknowns. If you need some help please scroll down to the example. If not, fill the 2 boxes below , then click on the "Go" button. Example As an example, let's say you have the following 3 equations to solve for the unknowns x , y , and z : 2x + 3y + 1/3z = 10 3x + 4y + 1z = 17 2y + 7z = 46 To enter the above system into the matrix solver you enter the number "3" into the small box for the number of unknowns/equations. Into the big box for the coefficients you enter the following numbers : 2 3 1/3 1.0e+1 3 4 1 17 0 2 7 46.0 Notice that each row represents one equation. Note, that for the coefficients you may enter either whole numbers ( like 2 ), fractions of whole numbers ( like 1/3 ), numbers with a decimal point ( like 46.0 ), or numbers in scientific notation ( 1.0e+01 which is the same as 10 ). After entering all numbers click on the "Go" button. You may check the solution : Which checks out.
Solar System Scope Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física. Many animations have been translated into Greek by Vangelis Koltsakis. Most animations have been translated into Hungarian by Sandor Nagy, Eötvös Loránd University.
