Respuesta :
csc x = 1 / sin x and cot x = cos x/ sin x ;
sin x * ( csc x - cot x * cos x ) =
= sin x * ( 1/sin x - cos x / sin x * cos x ) =
= sin x * ( ( 1 - cos² x ) / sin x ) =
= sin x * ( sin² x / sin x ) =
= sin x * sin x = sin² x ( answer)
sin x * ( csc x - cot x * cos x ) =
= sin x * ( 1/sin x - cos x / sin x * cos x ) =
= sin x * ( ( 1 - cos² x ) / sin x ) =
= sin x * ( sin² x / sin x ) =
= sin x * sin x = sin² x ( answer)
