Hello everyone, i'm looking at this proof and its making sence until the very last part, and it doens't friggin' work...the terms don't match up... Also is the notation I used correct in the proof, like does there have to be any vector notation I don't have or do you see anyhting you don't like? I'm proving the "The Vector triple product"
Here is my proof: Proof Look at the 2nd part of ax(bxc) > a1b1c3  a2b22c3 + a2b3c2 then look at the last part (c.ad)b  (b.a)c > a1b3c1  a1b1c3 + a2b3c2  a2b2c3 You see only 1 term isn't match up!! the a1b1c3 not equal to a1b3c1 whats going on? Thanks
