$let, \\ x = 1 + \sin(30) + \sin^{2} (30) + \sin^{3} (30)........ \\ \\ x = 1 + \sin(30) + \sin^{2} (30) + \sin^{3} (30) + \sin^{4} (30)........ \\ \\ x = 1 + \sin(30)( 1 + \sin(30) + \sin^{2} (30) + \sin^{3} (30)........) \\ \\ x = 1 + \sin(30)( x) \\ \\ x = 1 + \frac{1}{2}x \\ \\ x - \frac{1}{2}x = 1 \\ \\ \frac{1}{2}x = 1 \\ \\ x = 2 \\ \\ :.1 + \sin(30) + \sin^{2} (30) + \sin^{3} (30)........= 2$
