La función trigonométrica que relaciona el lado opuesto sobre lado adyacente es: a)Seno
b)Coseno
C)Tangente
D)Cotangente
E)Secante
F)Cosecante

Tangent (Option C in the given list)

Explanation:

The trigonometric function that involves the quotient of the opposite side to an angle over the adjacent side in a right angle triangle is the tangent function:

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.

answer: b.
