Answer:

mark me as the brainliest

Step-by-step explanation:

cosA / 1 - sinA/cosA + sinA/ 1 - cosA/sinA

=> cosA/ cosA - sinA / cosA  +  sinA / sinA - cosA / sinA

=> cos^{2}A / cosA - sinA  +  sin^{2}A / sinA - cosA

=> cos^{2}A - sin^{2} / cosA - sinA

=> (cosA + sinA)(cosA - sinA) / cosA - sinA

=> cosA + sinA => RHS
