comment Definition of function for integration
You're using p as an integration variable in a function that accepts p as an argument, and then call the function with an expression that can't be used as an integration variable. There is no discernible purpose to declaring p as a function argument here.

comment Output an Expression in terms of GoldenRatio
I assume you know about Simplify[9+4Sqrt[5] == GoldenRatio^6], right? The problem is that expressions in terms of GoldenRatio aren't unique. For example, Simplify[GoldenRatio^6 == 5 + 8 GoldenRatio] is also True, and I'm not sure whether you would accept both answers. A very simple answer would be to do this with any given expression expr: replace it by Simplify[expr /.Sqrt[5]->(2GoldenRatio-1)]

I'm voting to close this question as off-topic because it's not about Mathematica.

comment incuding graphics
You'll have to familiarize yourself with the language before trying to adapt legacy code to the new version. In particular, semicolon means CompoundExpression and will cause plots not to be displayed when followed by ;. Many people coming from other languages are confused about how semicolons work in Mathematica. It's important to read the introductory documentation first.

comment Copy and Paste Equations Mathematica
What I mean is that this cannot be done directly with built-in Mathematica commands, so it will require a palette or button that implements some code behind the scenes to create and decode the necessary meta-information that one needs to carry along with the PDf in order to be able to recreate the source from it. PDF is a display formatting language and by default doesn't retain enough information to allow meaningful round-trip conversion with Mathematica. So implementing this will take some work, and it's necessary to know more about what you really intend to do first.

comment Copy and Paste Equations Mathematica
If you have $\LaTeX$ installed, the linked prescription could be adapted. Or do you need something that doesn't rely on $\LaTeX$? For alternatives solutions, it may also matter what OS you're on.
