And if it was 75? Or maybe 103 or 150 º? North Design: Patricia Carla Mucelin Complete the table, using a calculator to assist. As the ship moves away from the lighthouse, the angle measurement becomes increasingly close to 180 °. In this case we say that the limit is 180, for the ship always moves in the direction North. What is happening with the values of the sine of the angle? Why the sine of the angle of 120 ° is equal to 60? Looking at the table, you can tell me what kind of change is occurring? What happens to the value of the sine when the angle gets closer to 180? But did you realize that there is a very large variation of situations involving triangles? You know you give some examples? To generalize these relationships involving triangles is that we put the triangles inside a circle. But why put the triangles inside a circle? The Greeks thought the Earth was the center of the universe, as recorded by Eudoxus (408-335 BC). The stars were signed to a huge crystalline sphere, which the Greeks considered to be the perfect shape: the sun, the moon, and the five visible planets were also trapped the ball. Ie, all celestial bodies formed large circles around the Earth.

A ako je to 75? Ili možda 103 ili 150 º? Sjever Dizajn: Patricia Carla Mucelin Ispunite tablicu, koristite kalkulator kako bi se pomoglo. Kao brod udaljava od svjetionika, mjerenje kuta, sve je blizu 180 °. U tom slučaju kažemo da je limit 180, za brod se uvijek kreće u smjeru sjevera. Što se događa s vrijednostima sinus kuta? Zato sinus kuta od 120 ° jednak 60? Gledajući tablicu, možete mi reći kakva promjena se događa? Što se događa u vrijednosti sinus kuta kad se približi na 180? No, jeste li shvatili da postoji vrlo velika varijacija situacijama trokuta? Znate li navesti neke primjere? Za generalizirati tih odnosa koji uključuju trokuta je da stavimo trokuta unutar kruga. Ali zašto mu trokuta unutar kruga? Grci su mislili da je zemlja bila centar svemira, kao što je zabilježio Eudoxus (408-335 BC). Zvijezde su potpisali za veliki kristalni sfere, koje su Grci smatraju savršeni oblik: Sunce, Mjesec i pet vidljivih planeta su također zarobljeni loptu. Odnosno, svi nebeska tijela formirana velike krugove oko Zemlje.
