"I have a macbook pro, 2011, 4G RAM, 2 GHZ 1T; yosemite 10.10.2
I put files in my trash I emptied. How to recover? I had not done my backup so it has not recorded in Time Machine."
See these threads, among many others, of some third party apps that might do a recovery.

A key point is not to use the computer until you decide upon a recovery process.
Also, you don't say what type of files you trashed.
If your files were created with a program such as Microsoft Office and you had Autosave enabled, you can still find backups or temporary copies of those files.
Some other programs such as Scrivener, create backups, as well.
