And it is quite easy to find counter-examples. For example, let ##y = x^2##. Then ##dy/dx = 2x \neq y/x = x##.mjc123 said:

Integration and derivation are two mathematical operations that are essentially inverse of each other. Integration is the process of finding the area under a curve, while derivation is the process of finding the slope of a curve at a given point.
Integration and derivation are important tools in science because they allow us to analyze and understand complex phenomena by breaking them down into simpler components. They are used extensively in physics, engineering, and many other fields to solve problems and make predictions.
The fundamental theorem of calculus is a fundamental concept in integration and derivation. It states that integration and derivation are inverse operations, meaning that the integral of a function is the derivative of its antiderivative. In other words, if we integrate a function and then take the derivative of the resulting function, we will get back the original function.
Integration and derivation are used in a wide range of real-world applications, such as calculating the velocity and acceleration of objects in motion, determining the area and volume of objects, and analyzing changes in quantities over time. They are also used in economics, statistics, and many other fields to model and analyze data.
Some common techniques for integration include substitution, integration by parts, and trigonometric substitution. For derivation, common techniques include the power rule, product rule, and chain rule. These techniques are used to solve more complex integrals and derivatives that cannot be solved using basic rules.
