( m+2 )sinA + (2m – 1)cosA = ( 2m+1 ) then find tanA. ( I first divided the eq. by cosA and then squared it . then replacing sec 2 A with 1+tan 2 A thus forming a quadratic eq. in tanA but then the discriminant could not be factorised. the answer of this ques is purely a fraction independent of m. so please solve this ques for me)
