From \(\sin^2 \theta+\cos^2 \theta=1\), we get \(\sin^2 \theta=1-\cos^2 \theta\). In exams, write the basic identity first.
Step 2
Why this answer is correct
The correct answer is A. \(1-\cos^2 \theta\). From \(\sin^2 \theta+\cos^2 \theta=1\), we get \(\sin^2 \theta=1-\cos^2 \theta\). In exams, write the basic identity first.
Step 3
Exam Tip
\(\sin^2 \theta+\cos^2 \theta=1\) से \(\sin^2 \theta=1-\cos^2 \theta\) मिलता है। परीक्षा में मूल सर्वसमिका को पहले लिखें।
