Substitute ##y'=z##, differentiate along ##\partial z##, and re-substitute ##z=y'##.Jozefina Gramatikova said:how do we differentiate y with respect to y' then?
You just have two variables, which I am going to call ##a## and ##b## (instead of ##y## and ##y'##). Thus, you haveJozefina Gramatikova said:how do we differentiate y with respect to y' then?

The fundamental idea behind the calculus of variations is to study the integrand as an abstract function of the variables involved. In this case ##y## and ##y'##, leaving to one side that as physical variables they are related.Jozefina Gramatikova said:how do we differentiate y with respect to y' then?
Differentiation with respect to a derivative is a mathematical process used to find the rate of change of a function with respect to its own derivative. In other words, it is a way to find how the rate of change of a function changes as its derivative changes.
Differentiation with respect to a derivative is important because it allows us to analyze the behavior of a function in relation to its own rate of change. This can help us understand the properties of a function and make predictions about its behavior.
To differentiate with respect to a derivative, we use the chain rule. This means that we take the derivative of the function with respect to its derivative, and then multiply it by the derivative of the derivative with respect to the original variable. This process can be repeated multiple times for higher order derivatives.
Differentiation is the process of finding the rate of change of a function with respect to its independent variable. Differentiation with respect to a derivative, on the other hand, is the process of finding the rate of change of a function with respect to its own derivative. This means that we are looking at how the rate of change of the function changes as its derivative changes.
Some real-world applications of differentiation with respect to a derivative include analyzing the behavior of stock prices in relation to their rates of change, predicting the growth rate of a population based on its current growth rate, and determining the optimal speed for a car to travel on a curved road based on its acceleration and the curvature of the road.
