1take any suitable one like 45°
hey anyone tell me how to rotate with some given angle if it is in all three direction like 2i+3j-8k plz give solution by taking example

11What angle do u want to rotate this vector by and any other conditions given??
11For an angle there will be infinite number of vectors which satisfy ur condition (IMAGINE A CONE)! Something else must be given.
1ok i m asking real problem abcdef is hexagon & pos. vector of a is i-j+2k then vector bc is
3rahul to rotate the given vector abt the origin at an angle of xy,yz,or zx plane
Ani can u give the eqn for the cone.
3rahul this hint will helps u
r(vec)=mod(r)unit vector along the direction of r
11dunno exactly but
take b as a general vector
modb=moda
then a.b=(modb)2cos60
axb=(modb)2sin60
u can get 3 eqations for three variables
am i correct
1ya correct but ong think by making fig. u get it is opp. of vector OA
