comment Nonexistence of a limit
This does not say that the limit does not exist. It states the condition for a given L to not be the limit. If you'd want to show that the limit does not exist, you would have to do it for all L as well

comment Problem with definite integral $\int _0^{\frac{\pi }{2}}\sin \left(\arctan \left(x\right)+x\right)dx$
@Asydot you are right, I guess I only tried the indefinite integral on wolfram.

both maple and wolfram can't find it, even the definite integral

comment Finding line that divides an area into equal halves.
The error is when you factor the $\sqrt{1-k}$. More precisely, look at the $(1-k)^{3/2}$.
