comment about the design of Part related to Association
I found more documentation on part with association. it is all here reference.wolfram.com/language/ref/Part.html about half way down the page. many examples.

comment about the design of Part related to Association
I think I figured it. To obtain the whole part, i.e. (key->value), one must use [[n;;n]] syntax or [[n;;]]. But if you use [[n]] this will only give the value at part n. The reason why [[n;;m]] work for both key,values at both n through m parts, is because of the ;; usage. So to pull both key+value, use ;;, else it will default to only the value at that part.

I agree. It is not consistent. May be it is a bug?

comment Order of operations
a/bc is always parsed as (a/b)*c, if you know a computer language that parses it as a/(bc) that would be very interesting to know.

comment AbsoluteOptions prints error messages in V10
@gwr I see. I was only using the example provided. For the example given, it did not give an error. There is a new post today on AbsoluteOptions problems also. mathematica.stackexchange.com/questions/68937/… so it seems there is more issue still with this. May be you can post your example as separate question? This will make it easier to track it on its own?

comment Solve a differential equation with an integral inside?
@NimblePawn added Laplace method. Not sure why -Sin[t] shows up in the ODE method vs. +Sin[t] in the Laplace now. But these are two methods I know about. The correct answer with zero IC should be the ODE based one. with -sin.
