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. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: In addition, I have prepared a small tutorial in using Flash to do Physics animations. It contains screen shots and embedded Flash animations, so the file size is a 173k. 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.

Animated Trigonometry. 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. СОФИЙСКИ УНИВЕРСИТЕТ (СУ) – 2012 г. » МАТЕМАТИКА за ВСЕКИ. МАТЕМАТИКА за ВСЕКИ.
