| Jan 25, 2022 at 15:54 | comment | added | Peter Taylor | This is clearly impossible unless all the $x_i$ are distinct and all the $y_i$ are distinct, in which case $$P_i(x, y) = \frac{\prod_{j \neq i}(x - x_i)(y - y_i)}{\prod_{j \neq i}(x_j - x_i)(y_j - y_i)}$$ Have I misunderstood something? | |
