Question

Find the value of sin265o +

sin225o + cos235o + cos255o.

B 1 Correct Answer Incorrect Answer

C 2 Correct Answer Incorrect Answer

D 4 Correct Answer Incorrect Answer

Solution

sin²65^o + sin²25^o+ cos²35^o + cos²55^o Using sin(90^o – x) = cosx and vice versa sin²65^o + sin²(90^o – 65^o) + cos²35^o + cos²(90^o – 35^o) = sin²65^o + cos²65^o + cos²35^o + sin²35^o = 1 + 1 = 2 (since, sin²x + cos²x = 1)
