Question

√((1 + sin A)/(1 - sin A)) = cos A/(1 - sin A)​

Answer 1

$\blue: </p><p>+cosAsinA=cosA1Hence∣cosA1−sinA∣=sA1−sinA.</p><p>Now −1≤sinA≤1Or 0≤1−sinA≤2.Hence∣1−sinA∣=1−sinA.Hence we get (1−sinA(∣cosA∣1−cosA1)=0</p><p>Or sinA=1 and A=2π or ∣cosA∣=cosA. This implies Aϵ[−2π,2π].Hence Ist and IVth quadrant.$
