WebCurl is an operator which takes in a function representing a three-dimensional vector field and gives another function representing a different three-dimensional vector field. If a fluid flows in three-dimensional space … WebMar 28, 2024 · curl [u_? (VectorQ [#] && Length [#] == 3 &)] := {D [u [ [3]], y] - D [u [ [2]], z], D [u [ [1]], z] - D [u [ [3]], x], D [u [ [2]], x] - D [u [ [1]], y]} EDIT This function is intended to deal specifically with lists of length 3. It can handle symbolic inputs, but these must be explicitly defined as having 3 components.

WebApr 6, 2024 · 5 Answers Sorted by: 4 If you want to drop the first element from a list a the statement Drop [a,1] returns a list the same as a without its first element. Note that this does not update a. To do that you could assign the result to a, eg a = Drop [a,1] WebCalculus. In calculus even more than other areas, the Wolfram Language packs centuries of mathematical development into a small number of exceptionally powerful functions. Continually enhanced by new methods being discovered at Wolfram Research, the algorithms in the Wolfram Language probably now reach almost every integral and … cryptography crack the code online game
