Question

prove that A x B = -B x A..

Answer 1

Use any values for A and B, and see if it is right
Image \(A\) is 5 and \(B\) is 6

\(A \times B = -B \times A\)
Sub the previous values
\(5\times6=-6\times5\)

See if it is right

Answer 2

i don't think so if it is right.. Can you please use this value to prove.. A=Axax, Ayay, Azaz and B= Bxax, Byay, Bzaz

Answer 3

What is axax, ayay, etc...?

Answer 4

that are vectors

Answer 5

this is A cross product B

Answer 6

Let
a=<a_1,a_2,a_3> and b=<b_1,b_2,b_3>


a x b = < a_2 * b_3 - a_3*b_2 , a_3*b1 - a_1*b3, a_1*b_2 - a_2*b_1>

Answer 7

now use this formula to show that
-b x a = a x b

Answer 8

thankss, i'm solving it right now..

Answer 9

figuer out 5 times 6=
and then figure out what -6 times 5=

Answer 10

@perl : can you please continue answering this, still i can't understand

Answer 11

Is that A and B stands for vectors? other wise it's wrong question!!!!

Answer 12

yes..

Answer 13

alright it is a cross product of two vectors!! let c be the cross product of the two vectos

Answer 14

can you just explain using these.. A=Axax, Ayay, Azaz and B= Bxax, Byay, Bzaz

Answer 15

ok let A(1,2,1) and B(-1,0,1)
