easy
$\sin 10^\circ + \sin 20^\circ + \sin 30^\circ + ... + $ $\sin 360^\circ $ का मान है
A
$1$
B
$0$
C
$-1$
D
इनमें से कोई नहीं
Solution
चूँकि $\sin 190^\circ = – \sin 10^\circ ,\;\sin 200^\circ = – \sin 20^\circ ,$
$\sin 210^\circ = – \sin 30^\circ ,\;\sin 360^\circ = \sin 180^\circ = 0$ इत्यादि।
