As given in the question, we have t, which is defined as x, y, comma, z, comma, w is equal to z plus 2v, comma 0, comma minus y plus w, comma, y.
00:20
So these are the given values and when we find our value for t squared, it is t multiplied by t where x comma y comma z comma w and this will be equal to t we have to place this value over here so z plus 2 w comma 0 comma minus y plus w plus w comma 1 and now i really for t squared x y z w will be equal to minus y plus w plus 2 y comma 0 comma minus 0 plus 5 comma 0.
01:16
And therefore for t square will be equal to 2y minus y minus v 0 comma 0.
01:30
And therefore t square will be equal to y minus w is comma 0 comma y minus y comma 0.
01:41
So this is our solution for value of t squared.
01:48
And then we can find here t cube with a similar way value for t cube has t into t squared which is t within the bracket y minus w 0 comma minus 5 comma 0.
02:09
So that is equal to minus 5 plus 2 into 0 comma 0 again minus 0 plus 0 .0 and that will be calculated as minus y 0 0 and 0...
