[@ahmed_zaman]

15: 48 : Incorrect way ❌ Mathematically, We can't cancel the power with base directly. Please correct it and instead of making formula ( a-b) ² by completing square.... Simply, take 2 common and then the "Coska" formula will be formed. Now, further put value of "Coskx" as a half angle identity , you'll get ( 1- sin square ka/2). This is an accurate way to make/close formula. 💯
