通过与1的合适因数相乘,将每一个表达式写成具有公分母(1-cos(θ))(1+cos(θ))的形式。 将11-cos(θ)乘以1+cos(θ)1+cos(θ)。 1+cos(θ)(1-cos(θ))(1+cos(θ))-11+cos(θ)⋅1-cos(θ)1-cos(θ) 将11+cos(θ)乘以1-cos(θ)1-cos(θ)。
【解析】 解析:∵$$ \frac { 2 + \cot ^ { 2 } \theta } { 1 + \sin \theta } = 1 , \therefore \frac { 1 + \cos ^ { 2 } \theta } { 1 + \sin \theta } = 1 . $$ ∴$$ 1 + \frac { 1 } { \sin ^ { 2 } \theta } = 1 + \sin \theta . $$∴...
【解析】 原式$$ \log _ { s i n \theta } ( 1 + \cot ^ { 2 } \theta ) = \log _ { s i n \theta } ( \frac { \sin ^ { 2 } \theta + \cos ^ { 2 } \theta } { \sin ^ { 2 } \theta } ) $$ $$ = \log _ { \sin \theta } ( \frac { 1 } ...
