Polynomial Construction from Sequences VIII

With all the knowledge learned in the previous posts, I have now made a convenient tool for inputting a list of points and outputting the polynomial that passes through each of them.

Add your points in the text field below, formatted as such: (x1, y1) (x2, y2) (x3, y3) ... Fractions are supported (ex. 2/5).

Then, press the button and the program will generate the polynomial for you! Here's a sample one to get you started:

(4, 16) (7, 49) (-2, 4) (0, 0)

P.S. doing math in Javascript is dumb
