hi swarna,

let the to vectors be A and B.

[a][b]sinq=6

[a][b]cosq=6^3

where 'q' is the angle bw them.

dividing both equations

tanq=6^2

therefore

q is

tan^-1(6^2)

hope u get it

plz dont foreget to rate me...........

A small mistake,On dividing the eqns.,we get,

tanq=1/36q=Angle between them=Tan^-1(1/36).
