My mind tends to wander during lectures, as it does on these videos. But on youtube, I can rewind!
-
@Kaminoeiennohigan just be patient
-
takes too long to get to the effing POINT.

@wasdtomove924 it's a line because it ends up being x/2+y/3=1 for it to be an ellipse it would have to be x^2 /2 + y^2 /3 = 1
-
i feel weird with the ''arc sin''
but great channel
-
@deathalert and your spelling..
-
Aiii luvz khanacademy. Helpt mi wit maii math
-
Wonderfully explained
-
in a problem like x = 2 sin ^2(t) and y = 3 cos ^2 (t)
can you use the trig identity to make it x/2 + x/3 = 1? to make it into an ellipse because i checked the back of my book for the graph and it was a line
