in the last video , we started on this problem right here , where we said let omega be a complex cube root of unity , and omega can not be equal to 1 . and so we figured out what all of the complex cube roots of unity were . we figured out -- well , we knew that 1 was one of them , and we used that to factor out this t... | and then the third one gives us 1 . so r2 would be 5 or 2 . and then r3 would be equal to 3 or 6 . | why should w^2 = conjugate of w ? |

so , in this problem , they 're telling us in outer space , the distance an object travels varies directly with the amount of time that it travels . and , that 's of course assuming that it 's not accelerating , and there 's no net force , and all of that on it . so , i guess they 're talking about a specific object . ... | so the distance is 3000 , so we have d is equal to 3000 miles . we have 3,000 miles is the distance , and that 's going to be equal to the constant of variation . the constant of variation times the time , times 6 hours . so , if we wan na solve for the constant of variation , we can just divide both sides by 6 hours . | in direct variation , as x increases , does y always have to increase ? |
