Senx(cosecx - senx) / tanx = ctgx - 1?
Senx(1 / sencillo - senx) / sen x / cosx = ctgx Senx(1 - sen2x / senx) / sen x / cosx = ctgx Cos2x / senx / cosx / 1 = ctgx Cosx / senx = ctgx Ctgx = ctgx.

Senx (cosecx - senx) / tanx = ctgx - 1?
Senx ( cscx - senx ) / tanx = ctg x - 1 ( senx * cscx - senx * senx ) / tanx = ctgx - 1 (senx * cscx - senx * senx ) = tanx * ctgx - tanx ( 1 - senx * senx ) = 1 - tanx cos ^ 2x = 1 - tanx tanx = 1 - cos ^ 2x tanx = sen…
