விளக்கம்:

cotθ+tanθ =secθ cosec θ

\cot \theta+\tan \theta

\Rightarrow>\frac{\cos \theta}{\sin \theta}+\frac{\sin \theta}{\cos \theta}

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

\sin ^{2} \theta+\cos ^{2} \theta = 1

=>\frac{1}{\sin \theta \cos \theta}

=>\frac{1}{\sin \theta} \cdot \frac{1}{\cos \theta}

= secθ cosec θ

L.H.S = R.H.S

cotθ+tanθ =secθ cosec θ  நிரூபிக்கப்பட்டது.
