No word's sir. Amazing video. You always approach the problem using concepts and not just random shortcuts

When a>0, on [a, 10] , this is uniformly convergent. Actually in this case Mn=1÷(1+n^2 .a^2)

But the exercise you have have given I am not able to do please help me Sir.

On [a, infinte], a>0 is (fn ) is uniformly cgt.
Reason: fn (x)=1/(1+n^2.x^2) is decreasing function on [a, infinite] and f (x)= lim (fn (x))=0 on [a, infinite] then sup|fn (x)-f (x)|=1/(1+n^2.a^2) which approaches o as n approaches infinte

Is it right sir??

Option 4 is not correct since LHS is lim of tan inverse n as n goes to infinity is π/2 not equal to RHS (0)

Sir In option 4 how can we take limit function as zero function? Firstly we have seen that limit function is a discontinuous function??? it takes values both 0 and 1 as well...so how to put lim fn(x)= 0 in option 4
