Explanation: lim_ (x\rightarrow 0)frac (1-cos2x) x^2 is 2. sin 2 (x)+sin 2 (x) 2sin 2 (x) is the left side. For the numerator, use the double-angle formula that will produce only one in the numerator when it is 1 - cos 2x/sin 2x = 1 - = Simplify the numerator. The second term is an integral of an odd function on a symmetric interval about 0. 積分を設定し解きます。.
