\frac{1-\tan ^{2} \theta}{\cot ^{2} \theta-1}=\tan ^{2} \theta

இடப்பக்கம்

=>\frac{1-\tan ^{2} \theta}{\cot ^{2} \theta-1}

=\frac{1-\frac{\sin ^{2} \theta}{\cos ^{2} \theta}}{\frac{\cos ^{2} \theta}{\sin ^{2} \theta}-1}

=>\frac{\frac{\cos ^{2} \theta-\sin ^{2} \theta}{\cos 2 \theta}}{\frac{\cos ^{2} \theta-\sin ^{2} \theta}{\sin ^{2} \theta}}

= \frac{\cos ^{2} \theta-\sin ^{2} \theta}{\cos ^{2} \theta} \times \frac{\sin ^{2} \theta}{\cos ^{2} \theta-\sin ^{2} \theta}

=>\frac{\sin ^{2} \theta}{\cos ^{2} \theta}

= \tan ^{2} \theta = வலப்பக்கம்

இடப்பக்கம் =  வலப்பக்கம்

\frac{1-\tan ^{2} \theta}{\cot ^{2} \theta-1}=\tan ^{2} \theta நிருபிக்கபட்டது.
