  ...And even when your hope is gone

  move along, move along, just to make it through

  (2015 self)

  Matrix A times col X, it DON’T equal col b 

  
  

   But wait! A times x hat equals some vector p

  
  

   B minus p is e A transpose e is naught 

  
  

   So now A transpose b equals A transpose p

  
  

   A transpose A x hat, is A transpose times b

  
  

   Aytee A’s invertible clap aytee A clap inv

  
  

   Ayta-inv at ax hat’s Ayta-inverse at b

  
  

   And matrix A times that’s A-ayta-inv at b 

  
  

   So we know A x hat’s A-ayta-inv at b 

  
  

  So now we know that p’s A-ayta-inv at b 

  
  

  Projection matrix Pay’s A times ayta-invat 

  
  

  Since Axhat is pay b; pay-inverse axhat’s b.
