gollark: Hmm, Desmos is fine with the simplified version, fun.
gollark: It's not some sort of optimizer thing, it's literally just Lagrange interpolation bodgily implemented in TypeScript.
gollark: Oh, here is the simplified version which stuff may actually let you plot: `(x - 2) * -1 / 120 * (x - 3) * (x - 4) * (x - 5) * (x - 6) + (x - 1) * 7 / 24 * (x - 3) * (x - 4) * (x - 5) * (x - 6) + (x - 1) * -9 / 4 * (x - 2) * (x - 4) * (x - 5) * (x - 6) + (x - 1) * 127 / 12 * (x - 2) * (x - 3) * (x - 5) * (x - 6) + (x - 1) * -1 / 8 * (x - 2) * (x - 3) * (x - 4) * (x - 6) + 104 * (x - 1) * (x - 2) * (x - 3) * (x - 4) * (x - 5)`.
gollark: If you like TeX, `\frac{\left( x-2\right)\cdot-1}{120}\cdot\left( x-3\right)\cdot\left( x-4\right)\cdot\left( x-5\right)\cdot\left( x-6\right)+\frac{\left( x-1\right)\cdot7}{24}\cdot\left( x-3\right)\cdot\left( x-4\right)\cdot\left( x-5\right)\cdot\left( x-6\right)+\frac{\left( x-1\right)\cdot-9}{4}\cdot\left( x-2\right)\cdot\left( x-4\right)\cdot\left( x-5\right)\cdot\left( x-6\right)+\frac{\left( x-1\right)\cdot127}{12}\cdot\left( x-2\right)\cdot\left( x-3\right)\cdot\left( x-5\right)\cdot\left( x-6\right)+\frac{\left( x-1\right)\cdot-1}{8}\cdot\left( x-2\right)\cdot\left( x-3\right)\cdot\left( x-4\right)\cdot\left( x-6\right)+104\cdot\left( x-1\right)\cdot\left( x-2\right)\cdot\left( x-3\right)\cdot\left( x-4\right)\cdot\left( x-5\right)`.
gollark: Your expression: (1 * (((x - 2) / (-1)) * ((x - 3) / (-2)) * ((x - 4) / (-3)) * ((x - 5) / (-4)) * ((x - 6) / (-5)))) + (7 * (((x - 1) / (1)) * ((x - 3) / (-1)) * ((x - 4) / (-2)) * ((x - 5) / (-3)) * ((x - 6) / (-4)))) + (27 * (((x - 1) / (2)) * ((x - 2) / (1)) * ((x - 4) / (-1)) * ((x - 5) / (-2)) * ((x - 6) / (-3)))) + (127 * (((x - 1) / (3)) * ((x - 2) / (2)) * ((x - 3) / (1)) * ((x - 5) / (-1)) * ((x - 6) / (-2)))) + (3 * (((x - 1) / (4)) * ((x - 2) / (3)) * ((x - 3) / (2)) * ((x - 4) / (1)) * ((x - 6) / (-1)))) + (12480 * (((x - 1) / (5)) * ((x - 2) / (4)) * ((x - 3) / (3)) * ((x - 4) / (2)) * ((x - 5) / (1))))
