Question:

What is the value of $\sin^2 60^\circ + \cos^2 60^\circ$? / $\sin^2 60^\circ + \cos^2 60^\circ$ का मान क्या है?

1.
0 / 0
2.
1 / 1
3.
3/2 / 3/2
4.
$\sqrt{3}/2$ / $\sqrt{3}/2$

Correct Answer: 1 / 1

By the fundamental trigonometric identity, $\sin^2 \theta + \cos^2 \theta = 1$ for every angle $\theta$, so the value is 1. / मूल त्रिकोणमितीय सर्वसमिका से, प्रत्येक कोण $\theta$ के लिए $\sin^2 \theta + \cos^2 \theta = 1$, अतः मान 1 है।
