CURSO GRATIS DE TRIGONOMETRIA PLANA
TABLAS TRIGONOMÉTRICAS
Cuando haciendo
cálculos como en algunos de los ejercicios anteriores decimos que la longitud
del seno o del coseno, etc., de un ángulo mide una cierta cantidad ¿cómo saber
cuántos grados mide su ángulo correspondiente?
Hoy en día casi
todos los estudiantes tenéis una calculadora de bolsillo a la que acudís con
mucha frecuencia para ahorrar, ojala, un poco de tiempo solamente.
En el caso de que
no dispongas de la citada herramienta es bueno
que tengas a mano una tabla donde encuentres los
valores de cualquier ángulo.
Toma los valores, aproximadamente, aceptando los dos primeros decimales.

longitud de arco equivale a la del radio.
