PROBLEMAS RESUELTOS

1. De la figura, calcula “”.

Resolución

Aplicando el teorema de Pitágoras
x =8 +15
2
2
2
2
x =64+225
x =289
2
x=17

Luego
8 8
Sen = →  = ArcSen

15 15
Cos = →  = ArcCos
17 17
8 8
Tg = →  = ArcTg
15 15
15 15
Ctg = →  = ArcCtg

2. Calcular “” si
Tg = 3Tg60+ 2Cos45

Resolución
Tg = 3Tg60+ 2Cos45
1
Tg = 3  3 + 2 
2
=
Tg = 3 1 4
+
  = arcTg4
