comment Result about Context is inconsistent with the description of “Power Programming with Mathematica”
I remembered now, this was asked before I posted an answer now, but deleted it. Will make community answer instead, just for documentation

comment How to send OUT output to stdout when running a script from command line on widows?
@bobthechemist ok, I see now what the problem was. Using -script "foo.m" was confusing things. I thought one should use -script. It looks from above that just simple "< foo.m" with the AppendTo[$Echo, "stdout"] will solve all the problems. Strange the docs do not show such simple examples for users. Very hard to find such info in documentation.

comment Animation of a geometric transformation
Could you please tell me what you get? the screen shot I pasted in the comment shows what I get. Clicking on it shows the output. I just copied and pasted your input, and the Plot I get, as you can see, is not the same as what you have. Windows 7, 64 bit, V 10.1

comment DSolve response with DSolve
Have you looked at the ODE themselves before passing them to DSolve? You can do this by splitting the cells, and evaluate the equations first to get an idea what is in them. Like this: !Mathematica graphics now one can see that the equations contain other derivatives of other dependent variables c2'[t],c4'[t],phi1'[t],phi3'[t],phi3'[t],phi4'[t]

fyi, the screen shot you show above (first one), is not what I get when I run your code under V10.1 !Mathematica graphics

this happens when you have large (long) output, and M shortens it. It is like etc....

comment NDSolve solving problem
You have second order ODE, but you only gave one IC. For numerical solver, it needs more one. (ps. the title of your question suggest it is a plotting problem, but there is no plotting issue here) (ps. actually the error message you get says the reason for the error :)

comment Solve ODE in State-space form
I do not know why the numerical gives these warnings, but your solutions are zero according to DSolve: w = 2; T = 2 Pi/w; a = 0.4; b = 4.0; d = 0.3; x[t_] := {x1[t], x2[t]} A0 = T {{0, 1}, {-a - b Cos[2 t], -d}}; sol = DSolve[{x'[t] == A0.x[t], x[0] == x'[0] == 0}, x[t], t] which gives {{x1[t] -> 0, x2[t] -> 0}} on V 10.1

comment How to stop Mathematica from turning .02 into 0.019999999999999997`
are you saying the correct valuate should be 0.02 exactly and M is not doing so? Could you post the source code to reproduce? hard to see the image, too small and need magnifying glasses to see.
