Why is SSE scalar sqrt(x) slower than rsqrt(x) * x?
.../y - 1/x^2) but they will be equally complicated.
Let's look at 1/sqrt(y) now. You can try f(x) = x^2 - 1/y, but it will be equally complicated: dx = 2xy / (y*x^2 - 1) for instance.
One non-obvious alternate choice for f(x) is: f(x) = y - 1/x^2
Then: dx = -f/f' = (y - 1/x^2) / (2/x^3) = 1/2 * x * ...

Using member variable in lambda capture list inside a member function
