Sabiendo que el coseno de un ángulo es 0,5 , es decir, cos α = 0,5.
¿Cómo calcularías la amplitud del ángulo α ?
α = tan-1 (0,5)
α = cos-1 (0,5)
α = sen-1 (0,5)
α = cos (0,5)
α = sen (0,5)

Sabiendo que la tangente de un ángulo es 1,45 , es decir, tan α = 1,45.
¿Cómo calcularías la amplitud del ángulo α ?
α = tan (1,45)
α = cos-1(1,45)
α = tan-1 (1,45)
α = tan (1,45)
α = sen-1 (1,45)

Sabiendo que el seno del ángulo α es 0,98.
Elige el procedimietno correcto para determinar la amplitud del ángulo α.
sen α = 0,98
α = cos-1 (0,98)
α ≅ 11,48º
sen α = 0,98
α = tan-1 (0,98)
α ≅ 44,42º
sen α = 0,98
α = sen-1 (0,98)
α ≅ 78,52º
sen α = 0,98
α = sen-1 (0,98)
α ≅ 110,52º
