let me guess Physics 1 with calc right??

3. IloveCharlie

Precalculus with Trig

4. godorovg

well this problem is a physics problem in a trig call wow!!

5. godorovg

okay I am going to try to help, because lucky for you I just learned this last night

6. IloveCharlie

Yay! Thank you so much!

7. godorovg

first I must must request a better scan of the problem so I can read it plz..

8. IloveCharlie

O.k. Does this work?

9. godorovg

10. IloveCharlie

Yes

12. godorovg

the drawing is the vector with the angle does this make sense to you?

13. godorovg

now with the mag being at 6feet and the angle that forms 25 degree angle what do we know about this?

14. IloveCharlie

Hmm, yes. So far it's making sense.

15. godorovg

hint take the vector as drawn and make triangle.

16. godorovg

after drawing the triangle where would the angle be on it, if 25 degrees is theda

17. IloveCharlie

So downwards :/

18. godorovg

yes

19. godorovg

20. IloveCharlie

I'm not sure what angle

21. godorovg

what type of triangle did you form?

22. IloveCharlie

An isosceles?

23. godorovg

yes

24. godorovg

brb phone

25. IloveCharlie

Ok thanks :)

26. IloveCharlie

You there?

27. IloveCharlie

@godorovg

28. godorovg

okay back now

29. godorovg

30. IloveCharlie

Oh no problem, just had to make sure you were still here :)

31. godorovg

call the search I am back lol

32. IloveCharlie

Haha

33. godorovg

be honest with me are really understanding what I am telling you?

34. IloveCharlie

So far... Kinda. But it really helps how you're helping me step by step

35. godorovg

okay what is unclear to you? explain plz

36. IloveCharlie

So just to be clear, you drew the vector with the angle which can make an isosceles triangle. So now what?

37. godorovg

if you read the problem it states there is a vector that has a 25 degree angle and maga of 6 feet. So, I took the what the problem and drew it out as to what the problem is asking for. The drawing is not to scare and could be a little off, but the point was to show you what it was saying

38. IloveCharlie

Oh o.k. Now I fully understand. So now, to solve

39. godorovg

the reason for me having you form a triangle is to get you not so scared of the vector is all

40. godorovg

because vectors are scary things if you don't know them

41. godorovg

well to solve this problem, I want you to try to tell me what step should be next? I won't be there when are you tested on this. Just try and I will guide you

42. godorovg

what does the problem want to know??

43. godorovg

hint pick out key points needed to solve, forget the rest.

44. godorovg

so we have angle 25 degrees and 6ft and the answers are 2. something so if this is trig what should be done now I would think we should considers sin or cos of 6times what you say?

45. godorovg

so in other words 6sin(25)=

46. IloveCharlie

Just a sec

47. IloveCharlie

2.53

48. godorovg

does that match the answer choice given?

49. IloveCharlie

Yes! Wow, thank you so very much :) And I understood your explanation from above

50. godorovg

your so welcome, bare with me is all I ask. Because I am trying to teach you and not give answers

51. IloveCharlie

Yes, I agree :) I will.
