Hello!
I want to raise my question one more time and hope for some help. Here are my thoughts.
That is what I still got when it comes to the left derivate:
cause .
Because I look at the derivate from the left site I will get
Is that correct?
Hello again!
I want to bring up my issue one more time to finally solve it! I want to understand how it works.
Here is what I have:
I want to calculate the left derivate.
I got from the integral which is (1)
The second inequality I get is from the advice from girdav which was to consider
This inequality can be put to and it leads to (2)
I got (1) and (2). How can I use these two inequalities for the left derivate? If I can replace the in (1) by something else which is bigger than k I would get the same derivate.
My conclusions should be correct until here but I donīt see how I can proceed from there.
I need a hint and I would be very thankful for that little hint to finally finish the work.
Thanks.

I donīt want you to solve me the thing but when you look at a problem for way too long you get more and more stuck and that is why I kindly ask you for some help.
I want to sum up my current thoughts:
I justify my last step by the fact that I consider those x with cause I want to calculate the left derivate and there is no minus before the integral cause .
Now I have got
Again girdav gave me the advice to look at but I can not use it here cause when I look at it I will get . There has to be a < involved somehow. I would get and I can not use that fact with my given inequality.
These are my thoughts and I am stuck here. Any ideas how I can proceed? Thanks.
