WebAug 16, 2024 · So to find sin (2A), based on the formula (1) above, we'll need to figure out the value of cosA. In this case since ∠A is in Q2, the value of cosA is negative. To figure out what cosA is, use your pythagorean identity: cosA = √ (1 - sin 2 A) = √ (1 - (4/5) 2) = √ (1 - 16/25) = √ (9/25) = 3/5 Since cosA is negative (since we're in Q2), cosA = -3/5 Web2. 104 views 2 years ago.
