A) \[{{\tan }^{2}}\theta ={{\tan }^{2}}{{\theta }_{1}}-{{\tan }^{2}}{{\theta }_{2}}\]
B) \[{{\cot }^{2}}\theta ={{\cot }^{2}}{{\theta }_{1}}+{{\cot }^{2}}{{\theta }_{2}}\]
C) \[{{\tan }^{2}}\theta ={{\tan }^{2}}{{\theta }_{1}}+{{\tan }^{2}}{{\theta }_{2}}\]
D) \[{{\cot }^{2}}\theta ={{\cot }^{2}}{{\theta }_{1}}-{{\cot }^{2}}{{\theta }_{2}}\]
