It is the operator used by Gottfried Liebniz, who developed calculus (in parallel with Newton).The "d" denotes a difference and, the full representation, dy/dx (not ddx), is used to represent a change in y divided by (per) a change in x. However, calculus goes further than comparing simple changes but uses these changes for smaller and smaller changes in x, that is, the limit of the change as dx approaches 0.
Derivative calculators are commonly used to help solve simple differential calculus equations. Generally, they are not able to solve complex calculus equations.
Assuming you mean what is the value of the derivative d/dx(a²x), then: d/dx(a²x) = a² The derivative (with respect to x) of d/dx(a²x) = d/dx(d/dx(a²x)) = d/dx(a²) = 0.
(a/b)'= (ba'-ab')/(b²)
The calculus operation for finding the rate of change in an equation is differentiation. By taking the derivative of the equation, you can find the rate at which one variable changes with respect to another.

It is a one word name ; 'Calculus'.
It is used in physics all the time. For example, acceleration is the derivative of velocity which is a derivative of position with respect to time. Calculating the amount of work done in a vector field (like an electrical field) also uses calculus.
Differential Calculus is to take the derivative of the function. It is important as it can be applied and supports other branches of science. For ex, If you have a velocity function, you can get its acceleration function by taking its derivative, same relationship as well with area and volume formulas.
In calculus, the derivative of a linear equation is a constant. y = 2x _ 5 dy/dx = 2 ( The constant).
In calculus, the relationship between velocity and time is represented by the derivative dv/dt. This derivative represents the rate of change of velocity with respect to time. It shows how quickly the velocity of an object is changing at any given moment.
There are lots of formulae in calculus, and they don't all begin the same way. Depending on what convention is used to express a derivative, the basic derivation formulae (which are BY NO MEANS all formulae used in calculus) usually start with d/dx, followed by some function or expression. In other words, "the derivative of ... is ...".
Newton is the named founder of Calculus. Yet there is controversy because it is claimed that Leibniz stole Newton's Calculus notes and took all credit for Calculus. But to this day Leibniz's integral and derivative notation is more commonly used that Newton's which was found confusing.
