解答一 举报 arcsin二分之根号3=π/3后面是arccos(-1/2)吧arccos值域是[0,π]所以arccos(-1/2)=2π/3arctan(负根号三)=-π/3所以原式=(π/3+2π/3)/(-π/3)=-3 解析看不懂?免费查看同类题视频解析查看解答 相似问题 arcsin2分之根号3加arccos(负2分之根号三)加arctan(负一)=?急 COS多少...
arctan(负根号三）=-π/3 所以原式=(π/3+2π/3)/(-π/3)=-3
arctan(负根号三）=-π/3 所以原式=(π/3+2π/3)/(-π/3)=-3
答案 arcsin二分之根号3=π/3后面是arccos(-1/2)吧arccos值域是[0,π]所以arccos(-1/2)=2π/3arctan(负根号三)=-π/3所以原式=(π/3+2π/3)/(-π/3)=-3相关推荐 1【arcsin二分之根号3+cos(-1\2)】的和再除以arctan(负根号三)等于多少?反馈...
