Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

I didn't understand these
do u know about dirichlet test or not
sin(n) is bounded . it is mentioned in 3 picture . so 1/log(n) is monotonicaly decreasing sequence and converge to zero . hence by dirichlet test this series is Convergent
you know that the value of sin(n) lies between -1 to 1 hence it is bounded
Any other doubt ??
how can we say that sin (n) / log(n) is decreasing
sin(n) will oscillate
now you should follow all this step
1
2.
3
4. this shows that Sin(n) is bounded .
any other doubt ??
you should improve your basic concepts
thank you 😊 I got it now
welcome dear 😜
