lim(n^2(cos1/n-1))(n趋向于无穷大)lim(n^2(cos1/n-1))(n趋向于无穷大)lim(n^2(cos1/n-1))(n趋向于无穷大)还是无穷,因为n^2比n高一阶.

n∈N,n≥2,求证:cos1/2*cos1/3 *.cos1/n > 2/3.
证明cos1/2+cos1/3+.+cos1/n>2/3
用两边夹法则证明:lim n趋于无穷时cos1/n=1
用洛必达方法则求极限lim n趋近于无穷大(sin1/n+cos1/n)^n
已知cosx>1/2x平方+1求证cos1/2+cos1/3+……+cos1/n>n+1/2n-3/2(n≥2,
lim(n+3)(4-n)/(n-1)(3-2n)
lim[(n+3)/(n+1))]^(n-2) 【n无穷大】

cos1/2*cos1/3*...cos1/n>2/3 难题.这是点拨上的一题 答案看不懂呢已知n∈N,n≥2,求证cos1/2*cos1/3*...cos1/n>2/3
lim (n!+(n-1)!+(n-2)!+(N-3)!+⋯..+2!+1)/n!其中n→∞
lim(n→∞) ((2n!/n!*n)^1/n的极限用定积分求是lim(n→∞) 1/n(2n!/n!)^1/n 不好意思
