Covering by Maximal Tori

In Exercise 4 of Chapter VII one showed that if T is a maximal torus in a matrix group G , then for any x ∈ G , xTx -1 is also a maximal torus. What we prove In this chapter is that if T is our standard maximal torus in one of our connected matrix groups G , then (†)
$$G = \mathop \cup \limits_{X \in G} {\text{ }}xT{x^{ - 1}}$$
showing that every element of G lies in at least one maximal torus. To say that \(G = \mathop \cup \limits_{X \in G} {\text{ }}xT{x^{ - 1}}\) is to say that given y ∈ G there exists x∈G such that
$$y \in xT{x^{ - 1}}$$
