含街It is widely believed that reading should be selective.

字成lim(n→+∞)√(n^2+2n)-n=lim(n→+∞)2n/[√(n^2+2n)+n]=1含街lim(x→π/2) secx-tanx
=lim(x→π/2) 1/cosx-sinx/cosx
=lim(x→π/2) (1-sinx)/cosx
=lim(x→π/2) [(1-sinx)(1+sinx)]/[cosx(1+sinx)]
=lim(x→π/2) (1-sin²x)/[cosx(1+sinx)]
=lim(x→π/2) cosx/(1+sinx)
=cos(π/2)/[1+sin(π/2)]
=0/(1+1)
=0

含街的四字成语

字成lim【√(n+1)-√n】
=lim1/【√(n+1)+√n】
当n趋于无穷 √(n+1)+√n趋于无穷
所以
lim1/【√(n+1)+√n】=0含街liman=liman+1 an+1=根号下an+6
即liman+1=根号下liman+1 +6
liman+1=3或-2 -2舍去(显然an>0)
所以lim=3字成Liming settles down after here

含街的四字成语

limn→∞(a11+q-qn)=12,含街
∴limn→∞qn一定存在.∴0<|q|<1或q=1.
当q=1时,含街a12-1=12,∴a1=3.
当0<|q|<1时,由limn→∞(a11+q-qn)=12得a11+q=12,∴2a1-1=q.
∴0<|2a1-1|<1.∴0<a1<1且a1≠12.
综上,得0<a1<1且a1≠12或a1=3.字成lim是极限英文Limite的前3个字母
