Why is the "Applications" tab no longer in my Finder?

Hey so i updated my MacbookPro from its original operating system to OS X Mavericks (version 10.9.1) because there was an update available. And just today i was went to uninstall a program that had expired, and i noticed that in my Finder, the "Applications" tab was gone. Usually on the top left corner of Finder there are tabs like "AirDrop", "Documents", "Downloads" etc. And applications is no longer there.

I need to uninstall a program, and i dont know how to without going to finder, then to applications.

If anyone knows why its gone, and how else you can delete programs on a macbook please comment!

Thank You!
