Simplify 1 − sin²θcos²θ, where cos θ ≠ 0.
1 − sin²θcos²θ को सरल कीजिए, जहाँ cos θ ≠ 0 है।
Answer और ExplanationAnswer and explanation
Answer: (C) 1
सर्वसमिका (Identity) sin²θ + cos²θ = 1 से 1 − sin²θ = cos²θ मिलता है।
1 − sin²θcos²θ = cos²θcos²θ = 1
✓
उत्तर 1 है।
From sin²θ + cos²θ = 1, we get 1 − sin²θ = cos²θ.
1 − sin²θcos²θ = cos²θcos²θ = 1
✓
The answer is 1.
