Let's say I have a plotted line, I use the x-coordinates of each point as index of the array and the y-coordinates as the values in the array. With this array, I need to figure out the line's minimum acceleration (the lowest point in the slope of the slope).

My initial idea was to begin finding the slope at every point by doing 

slope[i] = (line[i] - line[i-1]) / (i - (i-1))

with

slope[0] = 0

and then doing 

acceleration[i] = (slope[i] - slope[i-1]) / (i - (i-1))

with

acceleration[0] = 0

and then just sorting acceleration to have the lowest value first. But I'm not too sure if this will work.

  • Why not just use a language like R, MatLab, or even a TI-8x calculator? – Zarathuztra May 24 '14 at 22:52
  • This is needed for a project that's being done in PHP, it would be too much work for me and my team to incorporate a new language for our application just for this. And i'm not sure if my idea is the right way to do it. – user2361174 May 25 '14 at 05:23
