Find the angle between the following pairs of lines :(i) vecr=2hati-5hatj+hatk+lambda(3hati+2hatj+6hatk) and veck=7hati-6hatk+mu(hati+2hatj+2hatk)(ii) vecr=3hati+hatj-2hatk+lambda(hati-hatj-2hatk) and vecr=2hati-hatj-56hatk+mu(3hati-5hatj-4hatk)

Answer»


ANSWER :(i) `THEREFORE theta=cos^(-1)((19)/(21))`
(ii)`therefore theta=cos^(-1)((8)/(5sqrt3))`
