@EricLippert that article was super interesting. It brings up a great point that others have mentioned that the lack of parents really helps bring together plots
Jan 24, 2017 20:24
@Malvolio That's true. And I understand some of them were previously written stories too...of course, with a LOT of creative liberties taken hahaha
Jan 24, 2017 20:24
Obviously, some more recent movies like "Frozen" include the parents and then they die, which is why I feel that there is something more to this than just the money.

From what I always read, they simply couldn't afford to make Andy's father in toy story, so he simply didn't have one. Here is a link. quora.com/Toy-Story-movie-series/…

Finally a buzzfeed post about math :)
Apr 16, 2015 18:03
i got it
Apr 16, 2015 18:02
oh wow, i'm dumb
Apr 16, 2015 17:54
i'm so confused
Apr 16, 2015 17:54
okay serious problem. rotational rigid motion makes total sense with calculus and algebra. this is something i don't get though. we have a trapezoid with coordinates (-1,1),(-1, 4),(3,4), and (3,-3). the rotational isometry at R(1,0) is (0,-1). The rotational isometry at (0,1) is (1,0). Why?
Mar 30, 2015 21:04
@Owatch ah okay. i've done it before but not recently
Mar 30, 2015 21:02
@Owatch vaguely. is that what you did?
Mar 30, 2015 20:35
@owatc that works but you'd have to do partial fractions twice if you split
Mar 30, 2015 20:35
that's what i tried to do @mike
Mar 30, 2015 20:24
If you can make sense of this, @Owatch ? I can't. But that's apparently the solution

Mar 30, 2015 20:23
sorry moderator, but this is a long solution
Mar 30, 2015 20:21
it involves matrices
Mar 30, 2015 20:20
i found the way to do the partial fraction step, but it's cray. do you want to see it?
Mar 30, 2015 20:19
@Owatch same problem?
Mar 30, 2015 20:18
that would mean that it had an x intercept of 1, which is super not true
Mar 30, 2015 20:18
@Owatch no you can't do that.
Mar 30, 2015 20:17
@Owatch ah
Mar 30, 2015 20:17
@Owatch i
Mar 30, 2015 20:17
@Owatch if you want to go imaginary maybe
Mar 30, 2015 20:17
@Owatch not in the real system
Mar 30, 2015 20:16
i hate this geometry crap
Mar 30, 2015 20:16
if we only know that a quadrilateral has one pair of parallel and congruent opposite sides, what does it have to be? a parallelogram?
Mar 30, 2015 20:06
mhmm i'll be able to do this stuff again in the fall when i have to take real math again
Mar 30, 2015 20:04
example 4 might help
Mar 30, 2015 20:04
okay i got nothing. i'm in shape math mode right now. have you looked at paul's online notes?
Mar 30, 2015 19:58
i'm going to look this up really quick. give me a minute
Mar 30, 2015 19:53
yeah youre on your own for that part; i haven't messed with partial fractions in almost 2 years
Mar 30, 2015 19:51
what?
Mar 30, 2015 19:48
there's a starting point
Mar 30, 2015 19:48
@owatch
Mar 30, 2015 19:48
Mar 30, 2015 19:47
yeah sorry hang on
Mar 30, 2015 19:46
@owatch separate it into three integrals to start
Mar 30, 2015 19:41
@Ramanewbie this should help a little. let me know if you have questions after reading it algebra.com/algebra/homework/quadratic/…
Mar 30, 2015 19:41
@Owatch ohhh pretty. give me a few minutes to look at it
Mar 30, 2015 19:40
@Owatch what integral?
Mar 30, 2015 19:39
@Ramanewbie If there is no intersection with the x axis it involves using i as an imaginary number. do you really want to learn it?
Mar 30, 2015 19:35
fun :)
Mar 30, 2015 19:33
i gotchu @owatch
Mar 30, 2015 19:32
@Ramanewbie Sure. I second degree polynomial's equation is found by its x-intercepts, in this case x=5 and x=8. The equation of a second degree polynomial is written y=(x-r)(x-s), where r and s are the x-intercepts such that y=(x-5)(x-8). Distribute from there and you have your equation.
