¿Qué identidad se utiliza para transformar tan(x) en sen(x) y cos(x)?
tan(x) = sen(x) / cos(x)
tan(x) = cos(x) / sen(x)
tan(x) = sen(x) + cos(x)
tan(x) = sen(x) - cos(x)

¿Cómo se expresa cos(2x) en términos de cos(x)?
cos(2x) = 1 - 2sin²(x)
cos(2x) = cos²(x) + sin²(x)
cos(2x) = 2cos²(x) - 1
cos(2x) = cos(x) - sin(x)
