I've been programming for way too long.

Notes to self :-

  1. Never post to a question that begins with So.
  2. Never get into a discussion about Big-Oh.

comment What is the significance of the slope of the tangent line of a function? Why is the derivative so important?
@TazMan - In the case of polynomials yes all derivatives diminish inevitably because d/dx x^n = x^(n-1) (more or less) but that is a feature of polynomials. And yes, the derivative is the slope of the tangent which is the rate of change but the world is not all polynomials. There are curves that do not decay to nothing as you differentiate - there are also some that behave in very unusual ways but the core of my answer is the insight that the differential is the rate of change which is exactly the equation for the slope at any point.

@TazMan - Remember that derivative of sin is cos and vice-versa so not everything diminishes to zero like polynomials do.

comment Is there a name for sequences like these?
@MarcvanLeeuwen - Wow! I hadn't even noticed that - thank you for the addition. Interesting to note that starting at 0 using [7,-5] will only cover all integers starting with 6 but it certainly covers all integers.

It looks like another necessary condition is that the first and last numbers are always positive.
