விளக்கம்:

i)\tan ^{4} \theta+\tan ^{2} \theta=\sec ^{4} \theta-\sec ^{2} \theta

L.H.S = \tan ^{4} \theta+\tan ^{2} \theta

          \Rightarrow \tan ^{2} \theta\left[\tan ^{2} \theta+1\right]

           \Rightarrow\left(\sec ^{2} \theta-1\right)\left[\sec ^{2} \theta\right]

           \left[\because 1+\tan ^{2} \theta=\sec ^{2} \theta\right]

          \left.\tan ^{2} \theta=\left(\sec ^{2} \theta-1\right)\right]

             \Rightarrow \sec ^{4} \theta-\sec ^{2} \theta

              = R.H.S

L.H.S = R.H.S

\tan ^{4} \theta+\tan ^{2} \theta=\sec ^{4} \theta-\sec ^{2} \theta  நிருபிக்கபட்டது.
