cos135度等于多少值 - 百度知道
cos是余弦函数,通过观察135°可拆分成(180°-45°),所以cos135°=cos(180°-45°)=cos45°=(根号2)/2。 135度是第二象限角、根据一全(全是正的),二正(只有正弦是正数,余弦和正切都是负的),三切(只有正切是正数,正弦、余弦是负数),四余(只有余弦是正数,正弦和正切是负数),再用公式转化,135是45度的补角、所以可以得到,cos135°=cos(180°-45°)=cos45°=(根号2)/2。 cos135度等于多少值cos是余弦函数,通过观察135°可拆分 …

cos135度该怎么算? - 百度知道
cos是余弦函数,通过观察135°可拆分成(180°-45°),所以cos135°=cos(180°-45°)=-cos45°=-(根号2)/2. 还可以通过方法二:将135°拆分成(90°+45°),所以cos135°=cos(90°+45°)=-cos45°=-(根号2)/2. 扩展资料. cos的相关运算公式. 公式一:
