Answer 2

if Sin²A  + Cos²B = 1  then  Cos²A + Sin²B = 1

Step-by-step explanation:

Given :

Sin²A  + Cos²B = 1

To FInd :

Cos²A + Sin²B

Sin²A  + Cos²B = 1

as we know that

Sin²θ + Cos²θ  = 1

=> Sin²A = 1 -  Cos²A

  &  Cos²B = 1 - Sin²B

putting these value in Above Equation

1 -  Cos²A + 1 - Sin²B = 1

=> 2 = 1  + Cos²A + Sin²B

=> 1 = Cos²A + Sin²B

=> Cos²A + Sin²B = 1
