WebSolution Let us assume θ = 22. 5 0 So, 2 θ is 45 0. We know that the identity is sin 2 θ = 1 - cos 2 θ 2 - - - - - 1 On substituting the value of θ in equation 1, we get sin 2 22. 5 0 = 1 - cos 2 × 22. 5 0 2 = 1 - cos 45 ° 2 = 1 - 1 2 2 = 2 - 1 2 2 = 0. 146 [ 2 = 1. 414] So, sin 22. 5 0 = 0. 146 = 0. 38 Hence, the value of sin 22. 5 0 is 0. 38 . WebFor calculation, here's how to convert 22.5 as a Fraction using the formula above, step by step instructions are given below. Take only after the decimal point part for calculation. Then, divide that value by 1. Multiply both numerator and denominator by 10 (because there are 1 digits after the decimal point so that is 10 1 = 10).
