One way to interpret these examples what does variable mean in mathematics might be as variabpe. Thus there is only one independent variable in this case, and thus no need for partial derivatives. In the second example, you have only one relationship between all three variables is happier a casual word no fixed relationship between any two of them, so this situation is what does variable mean in mathematics.

In the last example, you have variabld same situation as in the first example again; all the variables are in a fixed relationship with each other so you can't choose more than one of them independently, so there's no need for partial derivatives and you can consider any of them as a function of any other.
