d/dx is an operation that means “take the derivative with respect to x” whereas dy/dx indicates that “the derivative of y was taken with respect to x”.

What does DX mean in differentiation?

“dx” is an infinitesimal change in x.

We can think of “dx” (read as dee-ex) as an infinitesimally small change in x. The “d” in “dx” should remind you of a delta ∆, which is the symbol for change. “dx has no numerical value.

What is dx and dy?

d/dx is an operation that means “take the derivative with respect to x” whereas dy/dx indicates that “the derivative of y was taken with respect to x”.

We denote derivative by dy/dx, i.e., the change in y with respect to x. If y(x) is a function, the derivative is represented as y'(x). The process of finding the derivative of a function is defined as differentiation. The slope of a function shows the derivative of a function.
