3,263,792 | I want to find the $$\lim\_{x\rightarrow \infty} (\sqrt x-x)$$
What I was thinking was to multiply by the conjugate since that's normally what you do with square roots, So I would get
$$\lim\_{x\rightarrow\infty} (\sqrt{x}-x)\cdot\frac{(\sqrt{x}+x)}{(\sqrt{x}+x)}$$
$=\lim\_{x\rightarrow\infty} \frac{x-x^2}{\sqrt{x}... | 2019/06/15 | [

] | You are correct with your idea stated in the comment, i.e., the line bisects the chord of $(0,0)$ to $(a,b)$, except you didn't mention the line is perpendicular to this chord. This is because the equal length (i.e., the radius) lines from the center of the circle to each end point of this chord, plus the chord line it... | Adding to John Omielan's answer, [according to the perpendicular bisector theorem](https://math.stackexchange.com/questions/2295360/prove-the-perpendicular-bisector-of-chord-passes-through-the-centre-of-the-circle), if a point is on the perpendicular bisector, then it is equidistant from the segment's endpoints.
