Answer:
Step-by-step explanation:
First we define two generic vectors in our space:
By definition we know that Euclidean norm on an 2-dimensional Euclidean space is:
Also we know that the inner product in space is defined as:
So as first condition we have that both two vectors have Euclidian Norm 1, that is:
and
As second condition we have that:
Which is the same:
Replacing the second condition on the first condition we have:
Since we have two posible solutions,
or
. If we choose
, we can choose next the other solution for
.
Remembering,
The two vectors we are looking for are:
