Still me with some limit problems...
Now I just don't any clues about what to do with trigonometric functions...
I have this :
I know it becomes this :
I know that the first one will tend towards 0 since sin(1/infinity) = sin(0) = 0
The second one, believe it or not, I'm not so sure about how to find its limit.
But I know that the limits of those two blocks isn't the answer of the question, that I have to look at their "sn"'s, but how would I be able to estimate sin(1) + sin(1/2) + sin(1/2) + ... and the other one that I won't write here ?
Same thing for the following, I'm clueless...
Please help, I'm kind of lost right now.
