Question

alguien que me ayude a resolver esto?

Answer 1

Respuesta:

                    $\cfrac{\sqrt{1-\sin^2{(A)}}}{\cot{(A)}}=\cfrac{1}{\csc{(A)}}\\\\\cfrac{\cos{(A)}}{\cot{(A)}}=\cfrac{1}{\csc{(A)}}\\\\\cfrac{\cos{(A)}}{\frac{\cos{(A)}}{\sin{(A)}}}=\cfrac{1}{\csc{(A)}}\\\\\\\cfrac{\cos{(A)}*\sin{(A)}}{\cos{(A)}}=\cfrac{1}{\csc{(A)}}\\\\\sin{(A)}=\cfrac{1}{\csc{(A)}}\\\\\cfrac{1}{\csc{(A)}}=\cfrac{1}{\csc{(A)}}$
