Question

Find the dot products (vector A+ 2Vector B). (2Vector A-3Vector B)​

Answer 1

Answer:

Given :    a+b=c   and    a+b=c

So,     c2=(a+b).(a+b)

Or     (a+b)2=a2+b2+2a.b

Or     a2+b2+2ab=a2+b2+2abcosθ

So,     cosθ=1

⟹ θ=0o

make as brilliant..

Answer 2

Answer:

Given here a+b=c and a=c

Explanation:

So cos =000
