# How to find the limit of cos(2x)/x as x approaches zero [duplicate]

Basicly the title. I know it's easy but I can't figure it out.  Not a duplicate has a 2x instead of x.

• what is $\cos 0?$ – Will Jagy Nov 15 '15 at 21:51
• It is when $x\to 0^+$? (i.e., only by positive values?) As asked, the limit does not exist. – Clement C. Nov 15 '15 at 21:54
• "Basically the title" is not a question. Please make your question's body self contained. If your entire question fits into the title, it is not a good question. – Asaf Karagila Nov 15 '15 at 22:39
• If its a short question then it can fit into the title. Doesn't mean its a bad question. – Earl Smith Nov 16 '15 at 23:53
