comment solution to Laplace Equation
To rephrase xzczd's comment: is your question related to the software product named Mathematica or is it about Maths only?

comment I have problem with Trigonometry
It's MathematicA not MathematicS. The former is a software product.

comment Using “we have” in maths papers
Actually, this advice is far from new. When I started to write my first article almost 25 years ago I consulted quite a few guides and found them to be unanimous there. Since then, I have been mostly using the APA publication manual, as that was the most appropriate for my research area. I have no real experience with European style guides, though I recall thumbing through the Oxford style guide.

comment Using “we have” in maths papers
I'd like to add that not only journal style guides advocate a more personal style of writing, but that a long list of academic style guides (like the Chicago manual of style) do the same. Still, the misunderstanding that scientific writing should be impersonal and dry persists.

comment Using “we have” in maths papers
Most style guides recommend the active voice over the passive voice, and most readers prefer it. But in some academic fields, especially the sciences, authors use a stilted and awkward style that replaces clear concise sentences like, "We performed the experiment," with circumlocutions like "The experiment was performed." Asked why they write like that, many scientists admit that they don't like it, but they are under the impression that journals require it. They are wrong. Of the journals that have style guides, the vast majority explictly ask authors to write in the ACTIVE VOICE.

comment Taylor series problem
A Taylor Series around 0 would work only for small i. Your solution of 2.055 would be incorrect anyway.

comment How to find trigonometry values using triangles in 1/2 form?
I am afraid you are asking this on the wrong site. This site is for the software product MathematicA. It is not about MathematicS.

comment How to plot this problem? From Greek Exams
@artes When I went to school we actually hand-plotted things when doing math. So plotting doesn't necessarily imply Mathematica. But we may give the OP the benefit of doubt. I'd appreciate some kind of acknowledgment by the OP that this question is indeed to be answered in the context of the Mathematica program.

comment Triangle mapped on a sphere in $\mathbb R^3$?
Shouldn't you at least specify what kind of mapping you want? I won't close it as per @mr.wizard's request, but I was very much tempted to do so. The question doesn't seem to be directly related to Mathematica and requires quite a bit of interpretative effort of the people here. Could have been much better.

comment Solve recursion $a_{n}=ba_{n-1}+cd^{n-1}$
I think you made a mistake somewhere. Mathematica finds me RSolve[{a[n] == b a[n \[Minus] 1] + c d^(n - 1), a[0] == 0}, a[n], n] ==> {{a[n] -> (c (b^n - d^n))/(b - d)}}
