Answer 2

@rajathsbhat @mathslover @Limitless @Yahoo!

Answer 3

what does lambda stand for?

Answer 4

wat is that @bronzegoddess

Answer 5

um wait lemme see

Answer 6

its a wedge that is used to denote skew communicative multiplication

Answer 7

Sorry @bronzegoddess i dont knw this...

Answer 8

that "wedge" is the greek letter lambda. lol
As for the question, i have no idea what skew communicative multiplication is. Sorry. :(

Answer 9

Plus i think that is "commutative".

Answer 10

its not meant to be lambda.. i choose lamdba because it was closest to the actual symbol
anyway an example from the book: \[(1,-3,2)\Lambda (4,1,3)= \begin{vmatrix}
i & j &k \\
1& -3&2 \\
4&1& 3
\end{vmatrix}\] and yes it should be commutative

Answer 11

Cross Product?

Answer 12

so the answer for the above would be = -11i+5j+13k
=(-11,5,13)

Answer 13

Aaahhh. The cross product.

Answer 14

cross product?

Answer 15

Yea, they call it that here.

Answer 16

Not to mention denoted with a cross... You just find the determinant of that matrix you provided, right?

Answer 17

terenz is right.

Answer 18

Just find the determinant.

Answer 19

yes, i did. I got (27,12,-7) but its wrong somehow because the 12 is meant to be -12

Answer 20

it is -12. Why aren't u getting it?

Answer 21

Hang on, I think the -7 is wrong too.

Answer 22

no, -7 is right.

Answer 23

Right, I accidentally added 2 and 4 instead of multiplying them... my bad... I think I'm getting drowsy, SORRY!

Answer 24

ah i get it :)

Answer 25

it's OK, terenz. Anyway, did u get -12, @bronzegoddess?

Answer 26
