(The above expression is read as "the derivative of y with respect to x", "dy by dx", or "dy over dx". The oral form " dy dx " is often used conversationally, although it may lead to confusion.) In Lagrange's notation , the derivative with respect to x of a function f ( x ) is denoted f' ( x ) (read as " f prime of x ") or f x ′( x ) (read as
Exponenciálna funkcia je dôležitá, pretože je to jediná funkcia (okrem funkcie =), ktorá je svojou vlastnou deriváciou, a z toho vyplýva že aj svojou vlastnou primitívnou funkciou: d d x e x = e x {\displaystyle {\frac {d}{dx}}e^{x}=e^{x}}

Here we look at doing the same thing but using the "dy/dx" notation (also called Leibniz's notation) instead of limits. 29/11/2009
The differential equation of the form is given as. d y d x = y x. Separating the variables, the given differential equation can be written as. 1 y d y = 1 x d x – – – ( i) With the separating the variable technique we must keep the terms d y and d x in the numerators with their respective functions. Now integrating both sides of the equation (i),
