The limit doe not exist, because f ( x n ) = 0 if x n = 1 n π and f ( x ) = 1 if x n = 1 π 2 + n π ( n N ), and both sequences converge to 0

How to appraoch solving this series?
I am given the following series and asked to solve it. n = 1 ( 2 ) n ( 2 n + 1 ) ! I recognize that this series is somewhat similar to the Taylor series for sinx which is n = 0 ( 1 ) n x 2 n + 1 ( 2 n + 1 ) ! .
However, I am not really able to relate these two series in order to solve them, especially since my series starts at 1 and once I rewrite the sinx series to match that, I am completely lost.

Get the limit from
lim x ( x π 2 arctan ( x ) sin ( t 2 ) d t )
asked 2022-07-27
the lower limit is 0 the upper limit is x on the first and thirdintegral. the second integral lower limit is 0 andupper limit is 2x.

We have the following limits:
lim x π 4 1 tan 2 x cos 2 x and lim θ 1 = θ 1 + sin ( θ 2 1 ) θ 2 1
Using L'Hôpital I obtained that the second limit is θ = 3 2 . For the first limit I was able to rewrite it to lim x π 4 ( 1 tan 2 ( x ) ) sec ( 2 x ), but I don't really know what to do with that.

If f ( x ) = x 2 and g ( x ) = x sin ( x ) + cos ( x ) then i have to find number of points(x) such that f(x)=g(x)
I write h(x)=f(x)−g(x). So h ( x ) = x 2 x sin ( x ) cos ( x )
h ( x ) = x ( 2 cos ( x ) ). Since 2 cos x is bounded so By taking limits as x goes to plus and minus infinity h′(x) goes to plus and minus infinity.which means h has root in between.
