Compute $\sin 5^\circ + \sin 10^\circ + \sin 15^\circ + \cdots + \sin 360^\circ$

Not as difficult  as it seems if we think about this

 

sum [ ( sin 5° + sin 10° + sin 15° +  ..... + sin 180° )  + ( sin355° + sin 350° + sin 345° + .... +sin 180° ) ]  =  0

 

And sin 0° = sin 360°  = 0 

 

Adding all these, the sum  =  0
