Answer 1

⇢Question:-

sin²5 + sin²10 + sin²15 + ••• + sin²85° + sin²(90°) =?

⚘Answer:-

.$\large\displaystyle \red{ { \rm{{\lim_{n \to \infty } {e}^{ - n} \sum_{ \mathbb{k = 0}}^{n} \frac{ {n}^{ \mathbb{k}} }{ \mathbb{k!}} }}}}$

⚘Explanation:-

ㅤㅤㅤ⇢ sin θ = cos (90° – θ)

ㅤㅤㅤ⇢ sin (90° – θ) = cos θ

ㅤㅤㅤㅤ∴ sin 85° = sin (90° – 5°) = cos 5°

ㅤㅤㅤㅤ∴ (sin² 5° + sin² 85°) + (sin² 10° + sin² 80°) + •••• ㅤㅤㅤㅤㅤto 8 terms + sin² 45° + sin² 90°

.

.

ㅤㅤㅤㅤ⚘⇢ So, your answer was 9×1/2
