Как найти синус определенного угла в градусах? Нужна сама формула, а не таблица Брадиса
Во-первых, переведите угол из градусов в радианы по формуле x = alpha * pi / 180 а потом воспользуйтесь разложением в ряд Тейлора. С достаточно хорощей степенью точности можно ограничиться формулой sin(x) = x — x^3 / 3
такой формулы нет. только брадис или инженерный калькулятор ой!
Константин! Sin x = x — x^3/6
Синус угла A минут B = (3.14/180) + B * (3.14/(180*60))) Так будет точнее. В некоторых случаях минуты (B) равны нулю, тогда остается только первая часть. В интернете есть готовые калькуляторы, например: <a rel=»nofollow» href=»http:///bradis/tablica-sinusov/» target=»_blank»>http:///bradis/tablica-sinusov/</a> или что-нибудь подобное
