Sin 10+sin20 +sin30+.....sin360 is equal to (A)1 (B)0(C)-1 (D)none of these

Question

Arun · Answer

sin 10 + sin 20+ sin30 +........... + sin330 + sin340 + sin 350 +sin 360 sin 10 + sin 20+ sin30 +........... + sin(360 –30) + sin(360 –20) + sin(360 – 10)+ sin(360) we know- sin(360 – theta) = –sin (theta) hence all the terms are cancelled out and sin 360 is remained so answer will be 0 + sin 360 (sin 360 = 0) 0 + 0 0 (answer) hence option B is correct
