LHS = tanA/1- cotA + cotA/1-tanA

=(sin/cos)/(1-cos/sin) + (cos/sin)/(1-sin/cos)

=sin^2/cos(sin-cos) +cos^2/sin(cos-sin)

=sin^2/cos(sin-cos) -cos^2/sin(sin-cos)

=sin^3- cos^3/sin*cos(sin-cos)

=(sin-cos)(sin^2+cos^2+sincos)/sin*cos(sin-cos)

=(sin-cos)(1+sincos)/sin*cos(sin-cos)

=1+sincos)/sin*cos

=1/sincos +. sincos/sin*cos

=cosecA.secA + 1

=1+secAcosecA

=RHS
