        Just give it to some students and do not tell them it's an open problem. Proof by delegation.

        Even if you do so , or you try the graphing idea related to the study of making this summation as a sequence , and you proctor the behavior of ( n+1)th term over nth term . It will be a big fail since the graph of sin^2 is sinusoidal like waves , so forget

        Since this is too simple, we will leave this proof as an exercise to the reader. QED.

        There is a slight possibility that sin^2(n) tends to 0 for some n. Hence it might actually not be convergent. A proof would put that to bed
