Nettet16. sep. 2024 · Recall from Theorem $\PageIndex{1}$ that an orthonormal set is linearly independent and forms a basis for its span. Since the rows of an $n \times n$ orthogonal matrix form an orthonormal set, they must be linearly independent. Now we have $n$ linearly independent vectors, and it follows that their span equals $\mathbb{R}^n$. NettetMath Advanced Math 5.
