If (1+sinA)/cosA=√2+1, then find the value of (1-sinA)/cosA

 Steps to solve If (1+sinA)/cosA=√2+1, then find the value of (1-sinA)/cosA

⇒(1+sinA)/cosA=√2+1

⇒{(1+sinA)/cosA}{(1-sinA)/cosA}=√2+1{(1-sinA)/cosA}

⇒{(1-sin^2A)/cos^2A}=√2+1{(1-sinA)/cosA}

⇒{cos^2A/cos^2A}=√2+1{(1-sinA)/cosA}

⇒(1-sinA)/cosA=1/(√2+1)

Hence the value of (1-sinA)/cosA is (1-sinA)/cosA=1/(√2+1)
