What is exactly the difference between and . And is the notation the same as the delta or the d notation? For example: and . Is it then true that with the delta notation you only differentiate f with respect to x and with the d notation you have to take in mind that y is also dependent on x? So, and ? And what is in this example? It is not really clear to me....
