## AmTran_Bus 2 years ago Find the Value for U, V, and W

1. AmTran_Bus

U=2i+3j+2k V=-2i+4j-k W=3i+3k

2. itsmylife

6 variables three equations , its not possible

3. RoseDryer

@itsmylife incorrect

4. itsmylife

@RoseDryer then solve it i would love to see

5. RoseDryer

6. itsmylife

hope you will solve it , see ya

7. AmTran_Bus

I am confused as well. This is for physics Here is the full question Given the following system of vectors U=2i+3j+2k V=-2i+4j-k W=3i+3k Find determinant by hand (done) FInd value of u x v explain the orientation of this vector in terms of U and V.

8. AmTran_Bus

@itsmylife here is the rest

9. itsmylife

well U V and W are expressed in the form of vectors i am not getting what you meant by finding value of U V and W

10. AmTran_Bus

Its just what the paper says. Here, let me attatch it.

11. AmTran_Bus

its #8

12. AmTran_Bus

gurrrrrr backwards

13. itsmylife

you misread the question it says find U*V , so find the cross product of vector U and V not U V and W lol

14. AmTran_Bus

ohhh. My bad. Um, can you guide me?

15. Spacelimbus

I was so lost by this myself (-: !

16. AmTran_Bus

@Spacelimbus I see what you were saying now....

17. itsmylife

|dw:1360256662345:dw| find the determinant

18. AmTran_Bus

Give me a sec.

19. itsmylife

in the top row its i , j , k

20. Spacelimbus

but for your defense @AmTran_Bus , I think the teacher should have written it out better to empathize with the vector product, like: $\Large \vec{a} \times \vec{b}=\vec{n}$

21. AmTran_Bus

is the bottom -2, 4, and -1? Ok, um...the letters on top...we have never done this before...the cross product.

22. itsmylife

its i(-3-8) -j (-2-(-4)) +k(8-(-6)) =-11i +2j +14k is your U*V

23. AmTran_Bus

@RoseDryer do you get this?
