Nettet3. feb. 2016 · lim x → 0 cosh ( x) is not 2. It's 1. – DanielWainfleet Feb 4, 2016 at 7:59 Add a comment 3 Answers Sorted by: 1 First remark : lim x → 0 + cosh ( x) = 1 and not 2 as you wrote (typo, I guess). You properly wrote coth ( x) = e 2 x + 1 e 2 x − 1 Now, remember that, for small y, e y = 1 + y + O ( y 2) so e 2 x = 1 + 2 x + O ( x 2) Nettetआमच्या मोफत मॅथ सॉल्वरान तुमच्या गणितांचे प्रस्न पावंड्या ...

But sin (x) --> x as x --> 0 is not a well-defined limit statement, and is in fact entirely meaningless. Your statement as translated mathematically would require knowledge of the upper and lower bounds for (sin (x)-x) for x in [-e,e], where e is 5 degrees (in radians).

As x goes to 0 from the positive side 1/x approaches infinity. But when x goes to 0 from the negative side 1/x goes instead to negative infinity. This means that the limit as x goes to 0 for Cos (x)/x is undefined as the left and right limits do not agree.
