1. The problem statement, all variables and given/known data Find a vector in the direction opposite to <-4,1,2>, that has a magnitude of 3. 2. Relevant equations I think that I did the first part of the problem correctly: <-4,1,2> magnitude= sqrt[ (-4)^2+1^2+2^2 ] = sqrt(16+1+4) = sqrt(21) (-4/sqrt(21), 1/sqrt(21), 2/sqrt(21) ) to get the opposite direction, I would just change the signs (4/sqrt(21), -1/sqrt(21), -2/sqrt(21) ) But I am confused at where to go from here. What does it mean "that has a magnitude of 3"? I may have approached this problem incorrectly. Any help would be great. Thank you for stopping by.
