Hmmm ...
you know that when x=1, the value of y=0, also the slope (y') is flat, and the change of slope (y'') is 0.
The only value you don't know at x=1 is y''', and that can be solved:
3y'''+ 5y''-y' +7y=0 ==> 3y'''+ 0 - 0 + 0=0 ==> y''' must equal 0
So, all given values are 0 and all flat at x=1 ...

Factor Theorem?
Hi Katy
According to the factor theorem,
For a polynomial P(x), x - a is a factor if P(a) = 0.
therefore substituting x=1 in the polynomial
P(x) =(x^3+3x^2+13x-15)
P(1) = 1+3+13-15
again substituting x=2 in P(x)
P(2)= 8+12+26-15

Problem Reduction with AO* Algorithm.
PROBLEM REDUCTION ( AND - OR graphs - AO * Algorithm)
When a problem can be divided into a set of sub problems, where each sub problem can be solved separately and a combination of these will be a solution, AND-OR graphs or AND - OR trees are used for
representing the solution.

Beyoncé Logic
Lots of great responses to my Doonesbury puzzler.
Implicitly, Alex was arguing, “If you are an independent, then you have a mind of your own.”
From which she concludes, “Conversely, if you are not an independent,” then you do not have a mind of your own.

Coherent trees: Is this result of Todorcevic correct?
up vote 15 down vote favorite
A family of functions $F$ is coherent when for every $f,g \in F$, $\{ x \in dom(f) \cap dom(g) : f(x) \not= g(x) \}$ is finite. A tree on $\omega_1$ is coherent if it is a coherent collection of
