we have to prove that LHS = RHS

So we will take LHA to prove,

sin⁴A × cos⁴A = sinA + cosA

sinA - cosA

sinA × cosA

sinA - cosA

[(sin²A)² × (cos²A)²]

sinA - cosA

(sin²A × cos²A)²

sinA - cosA

(1)²

sinA - cosA. [•sin²A ×cos²A = 1]

1. × sinA + cosA

sinA - cosA. sinA + cosA

sinA + cosA

sin²A - cos²A

sinA + cosA = sinA + cosA

hence proved.

i hope you understand this
