If OP=42 and direction cosines of OP→ are 27,37,−67, then P

If the length of the line segment OP=r and direction cosines of  OP¯are l,m,n then the coordinates of the point Plr,mr,nrHere,l,m,n=27,37,−67and r=42Therefore, the coordinates of the point P are as below. Here P27⋅42,37⋅42,−67⋅42=P12,18,−36
