L.H.S = tanx/1 - 1/ tanx + 1/tanx/ 1-tanx
= tanx /tanx -1/ tanx + 1 / tanx (1-tanx)
= tanx square/tanx -1 - 1/tanx (tanx-1)
= tanx cube -1/tanx (tanx -1)
= (tanx -1) (tanx square +tanx +1)/
tanx(tanx -1)
= tanx square +tanx +1/tanx
= tanx +1 + 1/tanx
= tanx +1+cotx.
= 1 + tanx + cotx.
Hence proved!
