comment Calculations with an exponentially-weighted moving average
I'm voting to close this question as off-topic because this question belongs on another site in the Stack Exchange network. It is not about using Mathematica.

comment How does Mathematica calculate sin(Pi/5)?
According to Goldstine, Ptolemy started with Sin[Pi/5] and Sin[Pi/3] when constructing his "table of chords," probably from Eu. XIII.10.

Also Galileo's Discourses and Mathematical Demonstrations Relating to Two New Sciences is in a similar dialogue form.

Welcome to Mathematica.SE! I suggest the following: 1) As you receive help, try to give it too, by answering questions in your area of expertise. 2) Take the tour! 3) When you see good questions and answers, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. Also, please remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign!

comment What’s the difference between Analytical and Numerical approaches to problems?
For some reason, I'm irritated that convention has settled on "analytic" instead of "symbolic." "Numerical" usually indicates an approximate solution obtained by methods of numerical analysis. "Analytical" solutions are exact and obtained by methods of symbolic manipulation, derived using analysis. The methods of numerical analysis are themselves derived using (symbolic) analysis. "Analytical" really fails to convey the intended distinction for me, since both approaches seem analytical.

comment How can I solve this spherical trigonometry problem?
In V10.3, this might work TravelDistance[CityData[{"Manila", "Manila", "Philippines"}], CityData[{"Phnom Penh", "Cambodia"}]] / Quantity[400, "Knots"].

comment How to solve equations to the fourth power?
@imulsion Here is a more sophisticated question of similar quality with 1/3 the upvotes (currently). This one is nearly a duplicate with 1/5 the upvotes. The vagaries of SE voting are renowned. (I do agree, however, that the AlecTeal's tone appears rude, and I think the argument that the question should be downvoted, implied IMO by the assertion that it is "not well researched," is off-base for the reason you cite.)

@user85361 The OP is referring to his six-year old child. It's colloquial in English.

comment differntial geometry
This site is for question about the software program called Mathematica (see mathematica.stackexchange.com/help/on-topic). This seems to be a question about mathematics. Is that right?
