Encuentra \(\sin\dfrac\pi3\) primero
OpenStudy (anonymous):
Answer 1.
arccos(sin 60)
arrcos(cos 30) ;as cos (90-x)=sinx
30
OpenStudy (anonymous):
sinπ/3 sería 60°
OpenStudy (kc_kennylau):
Su metodo functiona tambien

Usamos su metodo
OpenStudy (kc_kennylau):
Convierte \(\sin\dfrac\pi3\) a \(\cos\) primero
OpenStudy (anonymous):
So, the answer is 30°?
OpenStudy (kc_kennylau):
Si
OpenStudy (anonymous):
arcsin 1 = 90 degree
arccos 1/2 = 30 degree
Their difference 60 degree,
so tan 60= \[\sqrt{3}/2\]

usa la tabla

Yep! By the way, you don't say ''cuestion'' in Spanish, we say ''pregunta''! The right way to say what you wanted to say in Spanish is: '' Te refieres a la última pregunta?'' Ok, I'll use it!
OpenStudy (kc_kennylau):
gracias por la correccion :)
OpenStudy (anonymous):
No hay de que! back to the homework! I found that sin of 90° is 1 already, what do I have to do now!?! :o
OpenStudy (kc_kennylau):
cos 60 es 1/2 por tu tabla

Yep! Do I have to add them or what? :o
OpenStudy (kc_kennylau):
Veamos lo que tenemos ahora:
OpenStudy (kc_kennylau):
tan(arcsen 1 - arccos 1/2)
= tan(90-60)
OpenStudy (kc_kennylau):
Pienses que lo puedes hacer?
OpenStudy (anonymous):
30°! So it'd be \[\sqrt{3}/3\] ?
