Provide a generalization to each of the key terms listed in this section. First o , it would be best if you let d be a set that"s in r2, which is a plane region. Eld while it"s on r2 would be f (a function) and it"s assigned to every point, which are in the form of (x, y), while in d a 2d vector, which is in the following form: One of the best methods to picturing vector eld is by drawing an arrow that"s noting f (x, y) (the vector) while starting at a certain point, which is in the following point: It is actually impossible to have all of the points that are in the form of (x, y), however, you are able to create a reasonable impression of the function (f ) thanks to doing several points while in.
