cot(90^(@)-theta).cot theta का मान है : 01:35 (sin 63^(@))/(cos 27^(@)) का मान है : 01:53 sin theta=(sqrt(3))/(2), तो theta का व्यापक मान है : 05:17 यदि cos theta=(1)/(sqrt(...
theta=1/3(npi+pi2)Solve: cot2theta=tantheta
【解析】 $$ \cot \theta - \tan \theta = \frac { \cos \theta } { \sin \theta } - \frac { \sin \theta } { \cos \theta } \\ = \frac { \cos ^ { 2 } \theta - \sin ^ { 2 } \theta } { \sin \theta \cos \theta } \\ = \frac { \cos 2 \theta } { ...

根据Lemma 2, 不断进行展开,用 \pi_{g}(s_t) 和\pi_m(s_t) 来表示 G_\theta(\cdot|s_t) 和M_\phi(\cdot|s_t) ,有可以看出上式第一部分是最小化两个模型的交叉熵,促使两个模型的分布有更多的交叉。第二项等同于最大化生成器的熵,保证生成器能够尽可能的覆盖所有动作空间。但是直到现在我们...
