\(\rm \left(\frac{1}{\sin θ}+\frac{1}{\tan θ}\right)\rm \left(\frac{1}{\sin θ}-\frac{1}{\tan θ}\right)\)
பயன்படுத்தப்பட்ட வாய்பாடு:
(A2 - B2) = (A + B) × (A - B)
Cosec2 θ - cot2 θ = 1
கணக்கீடு:
\(\rm \left(\frac{1}{\sin θ}+\frac{1}{\tan θ}\right)\rm \left(\frac{1}{\sin θ}-\frac{1}{\tan θ}\right)\)
⇒ (cosec θ + cot θ) × (cosec θ - cot θ)
⇒ Cosec2 θ - cot2 θ
⇒ 1
∴ சரியான பதில் 1.
