WebJun 1, 2016 · Explanation: This can also be shown through the sine half-angle formula: sin( x 2) = ± √ 1 − cos(x) 2. Here, since we want to find sin( 7π 8), we know that x 2 = 7π 8 and x = 7π 4. sin( 7π 8) = ⎷ 1 −cos(7π 4) 2. Note that the ± sign has just turned into a positive sign: the sine of 7π 8 will be positive since 7π 8 is in the ...

What is the exact value of Sin(7pi/12) - Brainly.com
WebOct 20, 2024 · Question 1: Find the exact value of sin(7pi/4) Solution: As we have sin (7π/4) We can write as sin (2π – π/4) = sin(8π – π) / 4 = sin(7π/4) {7pi/4 lies in the 4th Quadrant} Therefore sin (2π – π/4) = sin π/4 {sin (180° – θ) = sin θ} = 1/√2. Question 2: Find the exact value of tan(7pi/4) WebFind the Exact Value sin((7pi)/12) Step 1. Rewrite as an angle where the values of the six trigonometric functions are known divided by . Step 2.
