It looks like you lost the minus sign in the second line that starts with W(x).Fatima Hasan said:

Abel's identity is a mathematical formula that relates the Wronskian of a set of functions to their derivatives. It is named after Norwegian mathematician Niels Henrik Abel.
To use Abel's identity to find the Wronskian, you must first take the derivative of each function in the set. Then, plug these derivatives and the original functions into Abel's identity. The resulting expression will be equal to the Wronskian.
The Wronskian is important because it is a tool used to determine if a set of functions is linearly independent or dependent. It is also used in solving systems of linear differential equations and in finding general solutions to these equations.
Yes, Abel's identity can be used for any set of functions, as long as they are differentiable. However, it is most commonly used for sets of linearly independent functions.
One limitation of Abel's identity is that it can only be used for sets of functions with a finite number of terms. Additionally, it may not be useful for finding the Wronskian when the functions involved are very complex or difficult to differentiate.
