Ma scanner isnt working so I will try posting da question gimme 5 minutes
The points A and B have position vectors a and b respectively, realative to an origin O. The vectors a and b are given by:
a= 2i-2j+k
b= 6i-2j+3k
i] obtain the value of a.b and hence find angle AOB, correct to the nearest degree.
Vector c has magnitude 12units and is such that c=pa, where p is a constant.
Vector d has magnitude 14 units and is such that d=qb, where q is a constant.
ii] Find the values of p and q
iii] Find the magnitude of d-c
srry i took tym =)
