I have four points that make a cubic bezier curve:
P1 = (10, 5)
P2 = (9, 12)
P3 = (24, -2)
P4 = (25, 3)
Now I want to find the inflection point of this curve. I googled and/but everyone is referring to one site: http://www.caffeineowl.com/graphics/2d/vectorial/cubic-inflexion.html
Unfortunately the applets are not working and I simply fail to put it all together. Could someone please be so kind to show me how to calculate the inflection point of my curve?
