You can put this solution on YOUR website!

The rule is one question per post. However, you did not ask any questions at all. You just listed a bunch of mathematical expressions with no information about what you are trying to do with them, what is giving you difficulty, and what you have tried so far yourself. Since you followed ZERO of the clearly specified instructions for posting, you get ZERO help.
