2023年7月12日 · Now, we know that sin²10° + cos²10° = 1 and similarly for other angles as well. Hence sin²10° and cos²10° are complementary, and so are other pairs. So, the sum of sin²10°, sin²20°, ..., sin²80° would be 4.5 (because 9/2 = 4.5) as the pairs of sin and cos values would sum to 1 for each 10 degree increment. Therefore, S = 9 - 4.5 = 4.5
