Welcome to the PF 
@Nipon -- we strongly prefer that you post using LaTeX math notation (see INFO, Help/How-To at the top of the page for a tutorial), but we are rounding up some help for you on this first post of yours. You have shown a lot of effort, which is the primary thing that we look for here. Posting your work in images is problematic for a number of reasons, though, so if you get a chance before there are more replies, it would be great if you could look over the LaTeX tutorial, and add a reply with the problem statement and your work in LaTeX notation. Thanks.

Upon further review, we will need this to be re-posted as a new thread using LaTeX notation. Just one example of a problem is what you are trying to say with "G" notation? Please read through the LaTeX tutorial thread and start a new thread with your question. Feel free to send me a message if you have questions about how to post (click on my avatar and select Start a Conversation). Thanks!
