Find the direction cosines and the direction angles for the vector
v = j - 5k
  • (cos a,cos b, cos c) = (0,-5/261/2,-1/261/2) and (a,b,c) = (p/2,2.94,1.77)
  • (cos a,cos b, cos c) = (0,1/261/2,-5/261/2) and (a,b,c) = (p/2,1.37,2.94)
  • (cos a,cos b, cos c) = (0,1,-.5) and (a,b,c) = (p/2,0,2.09)
  • (cos a,cos b, cos c) = (0,-1/261/2,-5/261/2) and (a,b,c) = (p/2,1.77,2.94)
  • (cos a,cos b, cos c) = (0,1,-5/261/2) and (a,b,c) = (p/2,0,2.94)
