A box is on a sloped ramp. The angle of incline of the ramp is 34 degrees, and the weight of the box is 58 Newtons. What is the parallel
force component of the box's weight that makes it slide down the hill.

Explanation:

parallel force component = mg sin (angle in degree)

=58 sin 34*

=32.433N

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.
