RE: diff() function
(11-09-2014 02:29 PM)DrD Wrote: 6.) diff(diff(f(x,y),y)) ---> -2 Modifying step (6.) thus: diff(f(x,y),y,y) works. In step (8.) (given by the y$2), y is sufficiently specified as the variable to use for each following derivative? -[or]-
In the case: ∂(diff(f(x,hpdiffx),hpdiffx),y) ---> 6 The variable of differentiation is specified only once. That's a lot to remember. The user guide description for the diff() topic could be expanded for more clarity. I think that about wraps up my interest in this function. Thanks Han, for taking all the time explaining details! -Dale- |
