I attended the Calculus course at my university, but neither I or my colleagues could understand what “exactly” is dx and its purpose. Thanks!

It’s more of a reference point than anything else, to my understanding it’s to help you know which variable you’re integrating or deriving, and is most useful in equations with multiples different variables. So for instance, if you have an equation where f(x)=3xy , the derivative would be dx=3y because the it’s the derivative of the function with respect to x
