Question

Anyone fluent with D operators in diff?

Answer 1

Why, do you have a question?

Answer 2

isnt D just notation for a derivative?

D(2x^2) = 4x

Answer 3

^pretty much. for any higher-order derivatives, there written out as \[D^n\], where n represents n, and \[D^n\] is the nth-derivative. Ex:

\[D^3 ( 4x^3)\] is the third derivative of 4x^3
