Anyone know why there is a "100% PROOF THAT GOD EXISTS - MUST SEE..." video in the suggestions?

You got one of the equations wrong at 2:35! Add a annotation cause it will confuse people like me!:)

good video

Sal should be the standard.

@shelbsterrox no they dont. they intersect at the center point of the hyperbola. In this case, he just happened to use the origin as the center.

"Hyperbolas, in some way, are more fun than any other conic sections." Sal is an awesome tutor!
-
at around the 9 minute mark you said x can never equal 0, does this mean x can NEVER equal zero when dealing with hyperbolas, or x cannot equal zero only in this problem?

Sitting here, taking notes... Oh how I miss notes!!
(Math 30 = Booklet and super fast lectures=no notes to take down..)

YOU ARE A LEGEND! (:

@ZewKnz Thanks man, that's the worst part about math it seems so complicated till you understand it then you feel dumb lol.
Great video, thanks. only a small correction on 10:30 x²=a² => x=+-a not x=+-sqrt(a).

thanks for spotting that. I added an annotation to clear that up.
