  I wish I understood these comments (:

• thumb_up thumb_down +92

  should have been integral of wayne from 0 to bat is batman

• thumb_up thumb_down +84

  Very good. So, spiderman.....

• thumb_up thumb_down +79

  question for the people who actually understand that question, is that shit actually usefull to know in your day to day life? i would find batman drawing skills more usefull personally.

• thumb_up thumb_down +70

  You don't need a constant if you're integrating a definite integral. He's integrating a function that's defined from zero to bat, therefore the constant is already defined within bounds of integration.

• thumb_up thumb_down +70

  lmao integration. Batman to Bruce Wayne xDDDDDD

• thumb_up thumb_down +70

  Why is the upper limit of integration, the same as the variable of integration?

• thumb_up thumb_down +66

  Half of these teachers need to go back to English class. Honestly, apostrophes are NOT that hard to use properly.

• thumb_up thumb_down +64

  You can't have the variable of integration in the bounds. He should have set up a dummy variable, like (bat-signal)_1 or something like that.

• thumb_up thumb_down +60

  lol batman

• thumb_up thumb_down +56

  Actually, it's an improper integral. Batman's awesomeness is infinite...

• thumb_up thumb_down +54

  Batman sucks and is not a superhero!!!

• thumb_up thumb_down +52

  who is the dumbass that came up with the problem and formula.

• thumb_up thumb_down +51

  dont click at the link of "very good resourse:" its a virus oder at least NOT A SITE THAT YOU WANT TO OPEN! jesus christ fuck this idiots

• thumb_up thumb_down +49

  He can't use the same variable in the limit and in the measure, that just doesn't make sense. What an idiot.

• thumb_up thumb_down +48

  he actually does need a constant during the use of the fundamental theorem of calculus although in the final answer he could be construed as a correct since the constants cancel we are not using numbers therefore he would need to show the subtraction of the variable constants(ensuring no loss of data due to imaginary numbers)

• thumb_up thumb_down +44

  The answer is '1'

• thumb_up thumb_down +44

  yup.

• thumb_up thumb_down +44

  using the variable you're differentiating with respect to in the boundaries of the integral, -5, assuming man is not a function of bat, integrating bat*man would give you man*((bat^2)/2) which when evaluated between 'bat' and 0 would give you still man*((bat^2)/2. which gives you one half of a bat squared man, not simply a man. differentiating bat*man with respect to bat however would give you just one man which would equate to bruce wayne.

  O.o AGGH STOOOP WITH THE FREAKY LANGUAGE!!11eleven!!!1!1

  Whoever think Batman Drawing skills are more important than the question do not know that they would be talking about this in real social gatherings only if many people at Intel did not have these skills.

• thumb_up thumb_down +38

  Actually, d/dBatSignal(BruceWayne)=Batman. That's the first fundamental theorem of calculus. Furthermore, Batman =/= Bat Signal. You'll notice, however, that the same logo is on his chest. I'm going to assume that it's something like BatSignal^(1/BatSignal) or something like that. You'd probably have to use L'Hopital's Rule or something anyway.

• thumb_up thumb_down +38

  THIS IS AWESOME!

• thumb_up thumb_down +38

  it's? its.

• thumb_up thumb_down +37

  That would equal one

• thumb_up thumb_down +36

  Batman is stronger than math, apparently...

• thumb_up thumb_down +35

  FAIL- incorrect apostrophe in the "it's"

• thumb_up thumb_down +35

  Lol

• thumb_up thumb_down +29

  This was a Temple Engineering Student and I know this because I was in this class. The teacher hung this answer up all over the building. As the commecials say, 'We could've gone anywhere but we chose Temple'

• thumb_up thumb_down +29

  d/dbat(Batman)=Wayne

• thumb_up thumb_down +27

  lolz. forgot the +c

• thumb_up thumb_down +25

  If this kid even understoodthe basics of integration it would be integral over Bruce Wayne from 0 to Bat logo, in order to become Batman. The d(Bat) is essentially multpilying the integrand (Bruce Wayne) over the entirety of the Bat suit (The summation from 0 to Bat) in order for the Bat suit to be attached to him, thereby becoming the Batman.

• thumb_up thumb_down +24

  Did this on my calc test, actually got a point for it.

• thumb_up thumb_down +23

  NA NA NA NA NA NA NA NA NA - Batman!

• thumb_up thumb_down +19

  it's? its.

• thumb_up thumb_down +18

  nnananananannana BATMAN!!

• thumb_up thumb_down +18

  "question for the people who actually understand that question, is that shit actually usefull to know in your day to day life? i would find batman drawing skills more usefull personally." I really hope you're still in high school. As for the question: Very. Mechanical engineer.

• thumb_up thumb_down +17

  Hmm, I would think you'd have to integrate Bruce Wayne to get Batman, since you add a "power" when integrating ;D

• thumb_up thumb_down +13

  Am I the only one pissed off by the fact that the teacher used 'it's' instead of 'its' ...? Teacher fail.

• thumb_up thumb_down +12

  OH SHI- I WAS JUST LEARNING INTEGRALS THIS WEEK LAL
