please solve this question urgent solution requirred

LHS=
(1 + sinA + cosA/ 1 + cosA - sinA)²
= 1 + sin²A + cos²A + 2sinA + 2cosA + 2sinAcosA
​    /  1 + sin²A + cos²A - 2sinAcosA - 2sinA + cosA
= 1 + 1 + 2sinA + 2cosA + 2sinAcosA
​   / 1 + 1 - 2sinA + 2cosA - 2sinAcosA
​= 2 + 2sinA + 2cosA + 2sinAcosA
   / 2 - 2sinA + 2cosA - 2sinAcosA
​= 2(1 + sinA) + 2cosA(1 + sinA)
  / 2(1 - sinA) + 2cosA(1 - sinA )
= (2 + 2cosA)(1+sinA)/ (2+2cosA)(1-sinA)
= 1 + sinA/1 - sinA
= R.H.S
Thumbs up Pls!!
