comment SumConvergence[((-1)^n)/(Sqrt[n] + (-1)^n), n] returns True in Version 10.2?
@clburchard When there is agreement about this we can add the "bugs" tag to your question. Done now.

comment Trying to solve an inhomogeneous differential equation, one of the initial condition equations returns “true” for some reason
You probably used an assignment (= ) in an earlier version of the code instead of an == so that one of the equations is now trivially true. Clear all the variables you've used and you should be back in business.

So, I assume you conclude that we see a bug here?

comment SumConvergence[((-1)^n)/(Sqrt[n] + (-1)^n), n] returns True in Version 10.2?
I believe you are right. I note that NSum using the AlternatingSigns method yields a slightly different result as the one above for Sum: NSum[((-1)^n)/(Sqrt[n] + (-1)^n), {n, 2, Infinity}, Method -> "AlternatingSigns"] ==> -2.67892. Sum with a finite limit yields the same set of results as your loop does.

comment How to Extract and Rearrange Elements in Doubly-Nested Lists
I may be mistaken here but wouldn't that be just NumSMatrix[[All,All,1]]?

comment Granular versus terse coding
You probably noted that there is this question is in the close vote queue (because it is mostly about opinions). I voted to keep this open, but more because of the quality of the question and the answers and the topic interests me than that I don't agree with the close reason.

comment How to prevent extrapolation in Manipulate?
Does Manipulate[If[t > Tmax[v0, theta], t = Tmax[v0, theta]]; Show[Trajectory[t, v0, theta Pi/180], PlotRange -> {{-2, 2}, {-2, 2}, {-1, 1}}, SphericalRegion -> True], {{t, 150, Style["Time", 10]}, 0, Tmax[v0, theta], 0.1}, {{v0, 0.25, "Velocity"}, 0, 1, 0.01}, {{theta, 63.3, "Polar angle"}, 30, 150, 0.1}, ControlPlacement -> Bottom] work for you?
