On the other hand, we also need to simplify the equation. Answer and Explanation: We are given the equation {eq}(\tan(\theta )+ 1) (\sec(\theta) - 2) = 0 {/eq}. Solving for {eq}\theta {/eq} in the interval {eq}0 \leq \theta <......
初级微积分 示例 热门问题 初级微积分 求出度数 tan(theta)=-1 tan(θ)=−1tan(θ)=-1 在等式两边都加上11。 tan(θ)+1=0tan(θ)+1=0 因为tan(θ)+1tan(θ)+1不是多项式,所以无法确定次数。 非多项式
【解析】 ∵$$ \tan \theta = - \frac { 1 } { 3 } , $$ ∴$$ \frac { \sin \theta } { \cos \theta } = - \frac { 1 } { 3 } $$① ∵$$ \sin ^ { 2 } \theta + \cos ^ { 2 } \theta = 1 $$② 由①②得$$\left\{ \begin{matrix} \sin \theta = \...
