Finding exact value of sin 22.5 degrees YouTube
so you get: sin2(22.5°) = 1 2 [1 − cos(45°)] sin2(22.5°) = 1 2 [1 − √2 2] = 2 − √2 4. and square root both sides: sin(22.5°) = ± √ 2 − √2 4 = ± 0.382. so sin(22.5°) = 0.382. Answer link. I found: 0.382 Using the half angle formula you get: sin^2 (theta)=1/2 [1-cos (2theta)] if theta=22.5° then 2theta=45° so you get: sin.

For sin 22 degrees, the angle 22° lies between 0° and 90° (First Quadrant). Since sine function is positive in the first quadrant, thus sin 22° value = 0.3746065. . . Since the sine function is a periodic function, we can represent sin 22° as, sin 22 degrees = sin(22° + n × 360°), n ∈ Z. ⇒ sin 22° = sin 382° = sin 742°, and so on.
