Find `| vec a- vec b|,\ if:| vec a|=3,\ | vec b|=4\ a n d\ vec adot vec b=1`

Find |vec a-vec b|,quad if :|vec a|=2,|vec b|=3 and vec avec b=4

Vectors vec a\ a n d\ vec b are such that | vec a|=3,\ | vec b|=2/3a n d\ ( vec axx vec b) is a unit vector. Write the angle between vec a\ a n d\ vec bdot

If vec a\ a n d\ vec b are two vectors such that | vec axx vec b|=3\ a n d\ vec adot vec b=1, find the angle between.

If | vec axx vec b|=4,\ | vec adot vec b|=2,\ t h e n\ | vec a|^2| vec b|^2= 6 b. 2 c. 20 d. 8

if | vec a | = | vec b | = | vec a + vec b | = 1 then | vec a-vec b |

Three vectors vec a , vec b , vec c satisfy the condition vec a+ vec b+ vec c= vec0 . Evaluate the quantity mu= vec adot vec b+ vec bdot vec c+ vec cdot vec a , if | vec a|=1, | vec b|=4 a n d | vec c|=2.

If | vec axx vec b|^2=( vec adot vec b)^2=144\ a n d\ | vec a|=4 , find vec bdot
