答案见上5.C 解析:$$ \frac { \sin \theta ( 1 + \sin 2 \theta ) } { \sin \theta + \cos \theta } = \frac { \sin \theta ( \sin \theta + \cos \theta ) ^ { 2 } } { \sin \theta + \cos \theta } $$ $$ = \frac { \sin ^ { 2 } \theta + \sin...
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 <......

(2)当两种线性均匀的导电介质内流有恒定电流时,分界面上电场线的曲折满足:$$ \frac { \tan \theta _ { 2 } } { \tan \theta _ { 1 } } = \frac { \sigma _ { 2 } } { \sigma _ { 1 } } $$其中 $$ \sigma _ { 1 } $$和 $$ \sigma _ { 2 } $$分别为两种介质的电...
答案见上解析 解法一:因为$$ \tan \theta = \frac { \sin \theta } { \cos \theta } = \frac { 1 } { 3 } $$,所以$$ \cos \theta = $$ 3sinθ,代入$$ \sin ^ { 2 } \theta + \cos ^ { 2 } \theta = 1 $$ 得$$ \sin ^ { 2 } \theta = \frac { 1 }...
