Handwritten derivation of f(x) = (sin x - cos x)/(sin x + cos x), dividing by cos x to get (tan x - 1)/(tan x + 1), rewriting as tan(x - pi/4), then differentiating to sec^2(x - pi/4) and simplifying to 2/(1 + sin 2x).

It is correct, but the solution is also simple if you differentiate the original function.
By the way, start and finish your latex formula with double $:

$$f(x)=\frac{sin(x)-cos(x)}{sin(x)+cos(x)} $$
$$f(x)=\frac{sin(x)-cos(x)}{sin(x)+cos(x)} $$
