Sir first of all thankyou very much for giving such a wonderful class free of cost. Sir there are no of students in our college who have joined coaching for mathematics but their concepts are not clear. They are saying even you are better from us without taking coaching. But I am really sure about my concepts after your lecture. Please continue this great work..👏👏👏👏👏👏👏

[@mandeepkumar8592]

4:00 / 8:46 ,
At this time stamp or point in question , should we not put n as infinity . so,
As, We know that 1/infinity = 0 ,
and equation become
[(1 + 0)^infinity] /3 , (1^infinity) = 1,
1/3.
answer 1/3 instead of E/3.
