[sage-edu] sagelet - calculus in two variables - differential

2009-03-09 Thread ma...@mendelu.cz
Dear readers of this group, I wrote a simple sagelet which describes approximation of a function in two variabels using differential. The sagelet is published at http://www.sagenb.org/home/pub/298/ I hope, somebody finds it useful in her/his courses. Any suggestions are welcomed. Robert Marik
