analysis - How find this limits limntoinftyleft(sinfracln22+sinfracln33+cdots+sinfraclnnnright)1/n


Find this limit
limn(sinln22+sinln33++sinlnnn)1/n





My idea:use
x=elnx


so we only find
limnln(sinln22+sinln33++sinlnnn)n

then
limnln(sinln22+sinln33++sinln(n+1)n+1)ln(sinln22+sinln33++sinlnnn)(n+1)n=ln(sinln22+sinln33++sinln(n+1)n+1)ln(sinln22+sinln33++sinlnnn)

then I can't works,Thank you
