Okay, i want to work out basically the values of a and b and make this work.
00:06
What we have here then is a times u.
00:11
That's going to be minus 2a, minus 3a, plus b times v will be minus b and 3b.
00:28
In other words, just times each number in u by a, each number in v by b, each number in v by and that is equal to minus 10, minus 6.
00:42
Now, corresponding parts, the i part here is minus 2a, i part here is minus b, i part here is minus 10.
00:53
So i know that minus 2a minus b has to equal minus 10 as the i part, the i components of the vector all the way across.
01:06
It times up by negative 1, it could be neater.
01:08
So 2a plus b will be 10 is my first equation...
