The magnitudes of the vertical and horizontal components of a vector are 11 and 17 centimeters respectively. Find the magnitude of the vector and the angle from the horizontal axis.

Explanation:

let the magnitude of the vector be |A|

|A| = ✓11^2 + 17^2 =

|A| =✓410

|A| = 20.23

theta =Tan^-1(11/17) =32.91°

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
