8cosx+8sinxtanx=8secx Verifying Trigonometric Identities When verifying trigonometric identities, we usually need to show that the left-hand side of an equation is equal to the right-hand side. To do this, we can use trig definitions (such as tanx...
Sin 函式傳回引數 (以弧度為單位的指定角度) 的正弦值。Tan 函式傳回引數 (以弧度為單位的指定角度) 的正切值。反函式Acos 函式傳回其引數的反餘弦值。 反餘弦值是以其餘弦值為引數的角度。 傳回的角度會以弧度為單位,範圍從 0 (零) 到π。
sin, 全称是 sine, 源自拉丁语 sinus, 它的涵义是“胸部、海湾”, sinus 是对阿拉伯语 jaib 的翻译。 jaib 的涵义就是“胸部”。jaib 实际上是 jb, 最初,古印度数学家Aryabhata 在他的梵语三角学著作里把jya-ardha(其含义是“弦”)简写成jya,或者它的同义词jiva.后来阿拉伯人把Aryabhata的梵文著作翻译成...
