Limite notevole sen (x) /x con x che tende a zero. Dimostrazione .

Brief demonstration of one of the most famous notable limits. For the demonstration it was necessary to recall the theorem of the comparison of limits, and obviously the basic notions of trigonometry that can be viewed at the following link.    • Goniometria - seno , coseno , tangente , a...   One of the most serious errors for the resolution of this notable limit is the application of the Hopital theorem, due to the fact that apparently the correct result is obtained. In reality it is a very serious error since to determine the derivative of the sine function, this notable limit is necessary, thus entering a vicious circle. Having said this I leave you to watch this video. #salvoromeo #limitsoffunctions #limitsnotable
