余切函数值能为(0)。当(cos x = 0)且(sin x eq0)时,余切函数(y=cot x=frac{cos x}{sin x}=0),此时(x=frac{pi}{2}+kpi,kin Z)。 如泥酣眠 2024-06-11 余切函数在(0)到(pi)内有零点吗? 回复 2024-06-13 有的。余切函数(y = cot x=frac{cos x}{sin x}),令(y = 0),即(...
正弦函数在第三象限和第四象限中为负。 余切函数在第一象限和第三象限中为正。θθ的解集仅限于第三象限,因为这是两组中唯一共同包含的象限。 解位于第三象限。 使用余切的定义求单位元直角三角形的已知边。象限将确定每一个值得符号。 cot(θ)=相邻对边cot(θ)=相邻对边 ...
