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)

cos α = 0,5

α = 30º

α = 25º

α = 60º

α = 180º

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
