This is my first post on the forum, but I have been reading this forum for at least 2 years now. It has always been very useful to read some of the posts you guys make.
However, now, it seems like I can't solve my problem simply by reading the forum...I would need a little extra help.
Here is how it goes:
(Note: Let bold letters be vectors)
I know that u=(u1,u2,u3), v=(v1,v2,v3) and w=(w1,w2,w3)
I have to prove that:
(Note: Let u,v and w, be vectors)
I tried to replace the norm of u times norm of v times norm of w by its equivalent using their values (u1,u2,u3), (v1,v2,v3), (w1,w2,w3).
But then, all I got was a huge equation and the strange impression that I am not even close from doing the right thing...
Anyone could help me head in the right direction ?
Thanks a lot !
