    f= 1/2L x Sqrt(T/mu).

    If you change, a variable keeping everything constant, you multiply both sides by the change. For example, if you keep everything the same but change the tension to 2N, you times both sides by sqrt(2).

    I get it, but I need someone to mathematically explain why you do this. In an old textbook it says something about proportions, but not fully.

    Thanks in advance.
