I am not sure whether elementary-proof is needed, but at least the usage should be clarified in the tag-info.

Q: $\lim_{x\to0}\frac{\sin x-x}{x^3}$ without de l'Hospital's Rule?

Przemysław ScherwentkeI know, how to calculate $$ \lim_{x\to0}\frac{\cos x-1}{x^2} $$ without differential calculus. Calculating $$ \lim_{x\to0}\frac{\sin x-x}{x^3} $$ using de l'Hospital's rule or Taylor expansion is also easy. Is there a method to calculate the previous limit without de l'Hospital's rule or stronge...

@PrzemysławScherwentke I see you have created new tag called (elementary-proof). It is recommended that a user who creates a new tag also creates tag-info - at least some basic info on the intended use of the new tag in the tag-excerpt. See, for example, this answer on meta. If some more details are needed, feel free to drop me a line in chat. — Martin Sleziak 1 min ago

BTW the tag has just been removed with edit summary: "No reason to create a new tag."
@PrzemysławScherwentke If you still think that this new tag could be useful, probably the best way to go is to start a discussion on meta. (To prevent repeated creation and removal of the tag.)
