## babydoll332 3 years ago Choose the graph of y =1/3 sin 2x

1. babydoll332

2. babydoll332

3. satellite73

the one that looks just like sine, but with amplitude $$\frac{1}{3}$$ and perios $$\pi$$

4. babydoll332

5. babydoll332

6. babydoll332

i plugged into the cal and it didnt show me either of the 4

7. saifoo.khan

What you YOU think it can be?

8. babydoll332

i think its the 3rd 1

9. saifoo.khan

it's sin.

10. saifoo.khan

|dw:1350520888570:dw|

11. babydoll332

the 4th one

12. babydoll332

:)

13. babydoll332

@saifoo.khan right?

14. satellite73

no

15. saifoo.khan
16. satellite73

it is the one with period $$\pi$$ not $$2\pi$$

17. satellite73

scared the hell out of me

18. babydoll332

ok it has 2 be the first one

19. babydoll332

meee too btw

20. saifoo.khan
21. satellite73

the fourth one has a longer period, the third one is not sine, i think it is the second one you are looking for

22. satellite73

something wrong with that boy...

23. satellite73

do you know how to tell the period from the graph?

24. satellite73

saifooooooo!

25. babydoll332

lol :) so its the 2nd one? right @satellite73

26. saifoo.khan

Which post is for me? lol.

27. saifoo.khan

@satellite73

28. satellite73

yeah that is the one with period $$\pi$$

29. satellite73

saifoo, it is all for you!

30. saifoo.khan

b is incorrect! D:

31. satellite73

really?

32. babydoll332

u guys are confusing how is it a then?

33. saifoo.khan
34. satellite73

i am sticking with B the one with period $$\pi$$

35. saifoo.khan

Satellite always confuse people

36. saifoo.khan

Hey! There will be 2 periods!!!

37. satellite73

you look like you just got back from your jr prom!

38. saifoo.khan

2 periods in 360* And no, it's Oscars. :D

41. satellite73

saifoo has had too much sid period of $$\sin(bx)$$ is $$\frac{2\pi}{b}$$ in your case it is $$\pi$$

42. saifoo.khan

SID = Sound Interface Device ? lol.

43. satellite73

there is no 360 on the damn graph. there is only numbers, not degrees! and it does all its business between 0 and $$\pi$$ making the period $$\pi$$

44. satellite73

|dw:1350521619165:dw|

45. saifoo.khan

Why it won't be A? http://drawception.com/pub/panels/2012/5-11/4acnsfph7c-14.png

46. satellite73

you are confusing this poor student!

47. babydoll332

i am a little lol :)

48. saifoo.khan

I'm a tiny.

49. satellite73

it won't be A because the period of A is $$\frac{\pi}{2}$$

50. satellite73

zero to one to zero to minus one to zero, length is $$\pi$$

51. babydoll332

ok thanks guys lol sorry my questions caused all this

52. saifoo.khan

Still don't get it

53. satellite73

|dw:1350521769442:dw|

54. satellite73

saifoo is very smart, he is just being dense at the moment

55. saifoo.khan

Dang! I get it. Kill meeeee!!!!!!!!!!!!!! -_- i forgot about 2pi/b

56. babydoll332

lol u guys crack me up

57. satellite73

whew!!!

58. saifoo.khan

It's 5:58am here. Bed is calling me.

59. satellite73

yikes! get some sleep, dream about periodic functions

60. saifoo.khan

lol. We are being taught cot graphs and stuff.

61. saifoo.khan

(back at school)

62. satellite73

ick glad it is you and not me

63. saifoo.khan

lol.
