👉 In mathematics, an "inter-differentiation" is a process where two or more functions are differentiated with respect to different variables. It involves using the chain rule and other differentiation rules to change one function into another, often in order to simplify calculations or find derivatives of composite functions.
For example, consider the following function:
f(x, y) = x^2
e^(y)
If we want to differentiate f with respect to x, we would use the chain rule to differentiate each term
