difference between on my own and my self and alone

 by myself, on my own, myself

I will do it myself = 'I will do it, no-one else will.'
I will do it by myself = 'I will do it, I don't need any help.'
I will do it on my own = 'I will do it, I don't need any help.'
I found the above from a closed thread(holboo) talking about the differences between the underlined parts.

If that's the case, does it mean by myself and on my own are in the same meaning?

Thank you.

difference between indicate, show , and reveal

reveal           -          дэлгэх

To reveal, to show, to indicate---shades of difference in meaning

Constructions like ‘the data reveal that’, ‘Table 1 shows that’, or ‘Figure 2 indicates that’ are common enough in research papers—and all are commonly used to connect a source (data, a table, a figure, etc.) to a statement supported by that source; however, the three verbs are not exactly synonyms but differ subtly in meaning.

‘Show’ is perhaps the plainest(илэрхий) of the three. Use it when the statement obviously(илт) follows from the source, as in ‘Table 1 shows that of the six months, December was the coldest.’ A glance at the source is all that is needed to know the truth of the statement.

‘Reveal’, on the other hand, means that the conclusion is not obvious but requires some thinking on the part of the reader—as it did on the part of the writer. The Oxford Dictionary of English defines ‘reveal’ as ‘make (previously unknown or secret information) known to others’. Therefore, use ‘reveal’ to convey that it took some analysis or interpretation of the data to arrive at the conclusion.

‘Indicate’ is similar to ‘show’ but introduces a note of uncertainty(эргэлзсэн): that the data leads you to suspect(сэжигтэн) something but you can't be sure. Use ‘indicate’ when you want to avoid a definitive(эцсийн) statement. However, do not use the word ‘indicate’ too often; if you do, your findings may be considered too tentative(тандсан) for publication.
