[^14.7+vec B=2hat i" and "vec A-vec B=4hat j" then angle between "vec A" and "],[vec B" is "]

vec(A)+vec(B)=2hat(i) and vec(A)- vec(B)=4hat(j) then angle between vec(A) and vec(B) is ?

If vec A =4 hat I + 6 hat j -3 hat k and vec B =- 2 hat I -5 hat j + 7 hat k , find the angle between vec A and vec B .

|vec a|=2,|vec b|=7 and vec a xxvec b=3hat i+2hat j+6hat k find the angle between vec a and vec b

If vec(a) = hat(i) - 2 hat(j) + 3 hat(k) and vec(b) = 2 hat(i) - 3 hat(j) + 5 hat(k) , then angle between vec(a) and vec(b) is

If vec A=hat i+hat j+hat k,vec B=4hat i+4hat j+4hat k and vec R=vec A+vec B then angle that vec R makes with vec A is

If vec a=4hat i+6hat j and vec b=3hat j+4hat k, then find the component of vec a and vec b .

If |vec(a) | =2, | vec(b) |=7 and vec(a) xx vec(b) = 3 hat(i) + 2hat(j) +6 hat(k) , then the angle between vec(a) and vec(b) is

let vec a = 2hat i +3hat j and vec b = hat i +4hat j then find projection of vec a on vec b
