spherical trigonometry

常見例句

Shenton's critics, it should be pointed out, can fall back on spherical trigonometry and astronomical -observations that date right back to Aristotle in 330BC.
有必要說明一下，早在公元前300年的亞里士多德時(shí)期，那時(shí)的球面三角學(xué)和天文觀測結(jié)果就批駁了珊頓的地平論觀點(diǎn)。

應(yīng)用球面三角法和方向余弦矩陣法分別推導(dǎo)出雙軸陀螺平臺的支架誤差公式，發(fā)現(xiàn)由這兩種方法推導(dǎo)出來的公式計(jì)算結(jié)果是一致的。
