Question

si: Seno = 40/41, calcula:
E= Csco + coto​

Answer 1

Respuesta:

Explicación paso a paso:

cscø = 1/senø = 41/40

cotø = cscø/secø

1/secø = cosø = cos(asen(40/41)) = √(1 - (40/41)²) = 9/41

E = cscø + cotø

E = cscø + cscø/secø

E = cscø(1 + cosø)

E = (41/40)(1 + cosø)

E = (41/40)(1 + 9/41)

E = 5/4
