A mass m hangs from a string. The person holding the string accelerates his or her hand to the right at an acceleration . The mass swings back and then hangs at a steady angle of θ as long as the horizontal acceleration is maintained. What is the angle θ ?

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.

its c its is a mixture of gases
