उत्तर
We know that, 1 radian is approximately 57º.
Also, the value of sin x is always increasing for \[0 \leq x \leq 90^\circ\] ( or sin x is an increasing function for \[0 \leq x \leq 90^\circ\] ).
Now,
\[1^\circ < 57^\circ\]
\[Or 1^\circ < 1\text{ radian }\]
\[ \therefore \sin1^\circ < \sin1\]
Hence, the correct answer is option \[\sin1^\circ < \sin1\].
