It would be clearer if you explained what $y$ is in the solution, rather than forcing a Reader to follow the link to find out.

comment Creating Truth tables
If you really want something to mechanically do your work for you, try this online generator of truth tables. What would be appropriate here would be asking for a more conceptual explanation.

comment Taylor Series Theorem
Note that if you set $x=a$ in the power series expansion shown, all but the first term vanishes (is zero). It requires justification to argue that the expansion converges and is valid at points other than $x=a$, but you cannot simply assert that "the proof only works in the instance that $x=a$". It is unclear why you think and say this. There is a proof that within a radius of convergence $R$, those $x$ within distance $R$ from $a$ will have a convergent series, and that convergent power series defines a unique "analytic" function in that region agreeing with all derivatives of $f$ at $a$.

comment Interaction of solid objects and change of trajectory
I think the change of tags that @MorganO made is about the most useful thing that can be said of such a general situation. The modeling of contact between two rigid bodies in motion is important, yet for a Question to be answered well in the brief format solicited here requires a more limited scope.
