1. angela210793

|it's graph is smth like this right?@erbil dw:1337624147315:dw|

2. angela210793

where did my pic go???????????????

3. apoorvk

@angela210793 you pic if awesome - i feel as if i suddenly understood demand and supply :D

4. apoorvk

Pacman chats and pic-hungry posts - OS is famished :/

5. angela210793

|dw:1337624331267:dw| @erbil come here pls

6. angela210793

@apoorvk stop making fun of me :P and help :P

7. apoorvk

am not making fun of it - it's actually awesome (straight faced) - I was looking at it for quite some time actually. :P

8. apoorvk

okay, so what do we do here?

9. angela210793

actually i think the pic is not right

10. angela210793

i think y=x is tangent to y=sinx

11. angela210793

i stuck -_-

12. angela210793

@apoorvk any idea???????????

13. apoorvk

lol, i am no good. what are we supposed to teach him though?

14. angela210793

lol...how to find the surface using defined integrals :P nvm though

15. apoorvk

Okay.. no probs. just a sec.

16. angela210793

tell me is my drawing right or y=x is tangent to y=sinx

17. apoorvk

Hmm, now. @erbil So we need to find the area under a curve using definite intervals... So, I guess you may be knowing that definite integral of a function within certain *limits* goves you the area under that curve within those limiting points - right?

18. apoorvk

*gives

19. apoorvk

@anxhela210793 yes, y=x would be tangent to sinx at x=0. (I was actually trying to sketch the graph here, but failed to do that with the mouse :P)

20. angela210793

well...none's as cool as i am :P:P so there's no surface at all :P lol wht now?

21. angela210793

@apoorvk ??

22. apoorvk

|dw:1337625841462:dw| Hmm better, though useless.

23. angela210793

lol xD

24. apoorvk

Btw, where is our pupil? Pupil? PUPIL????? @erbil ?? o.O

25. angela210793
