This is just AMAZING..not the physics part but the way you explain the physics part. My professor will try to "explain" this to us tomorrow but i have hunch it won't be this good.
-
Awesome but I wish this was HD
-
Wow, finally I know where that final equation comes from. Professors are just like "if you solve the differential equation you get yadda yadda yadda." I'm only just taking differential equations this semester (first class tomorrow) so I didn't really know what they were talking about. THANK YOU!

People like you deserve heaven!!

@lprk94 kinda lol.
-
@drmo92 he does :)
-
don't move the pointer so much I'm dizzy :D
-
@drmo92 You have to account for when coswt is equal to zero. The minus sign can be eliminated because it is constantly -1 and the A can be eliminated because amplitude is never zero. But coswt can possibly be zero. And we all know you can't divide by zero... Or the world will end..
-
Can someone explain clearly why x(t) intuitively is equal to Acos(wt) ? Am I just lacking intuition here?
-
AT 8:07 WE HAVE HE ELIMINATE FACTORS ON EACH SIDE, BUT WHY WHY NOT ELIMINATE COSWT ASWELL?

Thank God for his slow-ness so we slow people can understand. Since you're Einstein, what are you doing here? Write a Nobel Prize Theory and leave us alone.

My professor was terrible at explaining this, but everything you said made perfect sense-- thanks.
