We can vary x and ask, "By at least how much does the approximating chord have to be off for any x?" When a specific x achieves this minimum, the resulting chord with delta signature {{nowrap|+δ<sub>1</sub> +δ<sub>2</sub> ... +δ<sub>''n''</sub> | We can vary x and ask, "By at least how much (in the linear domain) does the approximating chord have to be off for any x?"
