prove that [a+b b+c c+a] = 2[a b c] Share with your friends Share 3 Manbar Singh answered this I think your question is,For any 3 vectors a→, b→ and c→, prove thata→+b→ b→+c→ c→+a→ = 2a→ b→ c→Here is tha answer:LHS =a→+b→ b→+c→ c→+a→=a→+b→×b→+c→ . c→+a→=a→×b→+a→×c→+b→×b→+b→×c→ . c→+a→=a→×b→+a→×c→+b→×c→ . c→+a→=a→×b→.c→ + a→×b→. a→ + a→×c→.c→ + a→×c→. a→ + b→×c→.c→ + b→×c→ . a→=a→ b→ c→ +a→ b→ a→ +a→ c→ c→ + a→ c→ a→ + b→ c→ c→ + b→ c→ a→=a→ b→ c→ + b→ c→ a→=2a→ b→ c→ 1 View Full Answer
