hey !!

Given ..

sinA/1+cosA=1 -cosA/sinA

sin²A =1 ² - cos²A [ by using cross multiplication rule ]

Then..

sin²A = sin²A [•° • 1 - cos²A =sin²A ]

now here LHS =RHS prooved .
hope it helps you .!!

2nd method is .

like rationalising process

so...

from LHS

sinA/1+cosA ×1 -cosA/1 - cosA

=> sinA(1+cosA)/(1 - cos²A )

=>sinA×(1+cosA)/sin²A

=>1+cosA/sinA RHS prooved .
