calculus - How to find limntoinftyfracsin(1)+sin(frac12)+dots+sin(frac1n)ln(n)


lim




I tried applying Cesaro Stolz and found its (\sin 1/(n+1))/\ln(n+1)/n where \ln is \log_e and it would be 1 and so the limit is 0, but in my book the answer is 2. Am I doing something wrong or can't Cesaro be applied here?
