## hba Group Title Can any one tell me about tensor and phasor ? one year ago one year ago

1. hba Group Title

I studied in high school that there are four types of measuring quantities 1)Scalar 2)Vector 3)Phasor 4)Tensor I studied about Scalar and vector in great detail,but,i did not get to know about Phasor and Tensor.

3. hba Group Title

@sauravshakya Yes ?

4. hba Group Title

@Callisto

5. UnkleRhaukus Group Title

um a tensor is a type of matrix

6. hba Group Title

tensor- how i get before a test phasor- star trek weapon can be turned up to lethal or stunning strength your welcome <3

8. hba Group Title

your'e*

9. Spectrum Group Title

rofl ty

10. Spectrum Group Title

you're* :)

11. hba Group Title

ty.

12. UnkleRhaukus Group Title

i dont know about phasors, but i have also heard of spinors

13. hba Group Title

Hmm.Thanks a lot @UnkleRhaukus :)

14. UnkleRhaukus Group Title

wikipedia tells me that a phasor is just a sinusoid

15. hba Group Title

Just a sinusoid ?

16. hba Group Title

Lemme check.

17. UnkleRhaukus Group Title

i would like to know the difference between a spinor and a tensor (they are some kinda matrix) , but my studies havent brought me to that level yet

18. hba Group Title

a phasor or sinor is some sort of a sinusoid.

19. hba Group Title

I don't know what Spinor is though.

20. UnkleRhaukus Group Title

21. hba Group Title

Well,I have just completed high school,So you cannot expect that from me lol :P Spinors,twistors and quaternion are something i have not studied yet :(

22. UnkleRhaukus Group Title

they look a bit scary to me , but i aim to one day have a deep understanding of these concepts , one day

23. hba Group Title

I also hope to have an understanding about them one day :) @Callisto Can you help us ?

24. Callisto Group Title

@hba Note that I'm just at the same level as you. How am I supposed to know that?

25. hba Group Title

@Callisto I have not joined Uni yet and you are done with a whole semster.

26. hba Group Title

semester*

27. Callisto Group Title

I'm sorry. I took the calculus course in the first semester, haven't taken the linear algebra yet.

@hartnn Lifesaver :'(

29. hba Group Title

@hartnn Tell me about Phasor and tensor((they are some kinda matrix) ?

30. hartnn Group Title

phasor is just a phase vector, like $$A \sin (\omega \theta)$$ is a phasor, one which has amplitude, frequency and phase.

31. hartnn Group Title

32. hartnn Group Title

i meant $$A \sin (\omega t +\theta)$$ as phasor....

33. hba Group Title

Um,I read something like this from Wiki. Can you tell me something more ?

34. hartnn Group Title

i can't tell you more than wiki :P this was never taught to me...

35. hba Group Title

36. hba Group Title

@ajprincess Here

37. ajprincess Group Title

Really sorry @hba. I too have no idea:( Guess they will be teachng me these in my second yr.

38. Raja99 Group Title

All the above three quantities are one and same..in the sense all represents physical quantities

39. hba Group Title

@experimentX Can you help ?

40. experimentX Group Title

scalar is a tensor of rank zero

41. experimentX Group Title

vector is a tensor of rank 1 here is a better explanation http://mathforum.org/library/drmath/view/51503.html

42. hba Group Title

43. experimentX Group Title

I am not sure about phasor, at least it's not a vector according to wikipedia

44. hba Group Title

Hmm,Thanks a lot :)

45. experimentX Group Title

sorry I don't have much experience in tensor calculus.

46. hba Group Title

No worries c:

47. UnkleRhaukus Group Title

so tensors are always square matrices?
