    Given L.H.S

      =  (1 + tan2A) / (1+cot2A)

    We know  sec2A - tan2A  =  1

    so sec2A  =  1 + tan2A

    Similarly  cosec2A - cot2A  =  1

    cosec2A  =  1 + cot2A

     

    Now replace 1 + tan2A with  sec2A and  1+cot2A with cosec2A

      =  sec2A / cosec2A

      =  (1/cos2A) / (1/sin2A)

      =  sin2A/cos2A

      =  tan2A

    (1 + tan2A) / (1+cot2A)=tan2A
