L.H.S

Let theta be = x

=>

(1+Cosx)×(Sinx) + Tanx(1-Cosx)
____________________
1² - Cos² x

=>

Sinx + Sinx × Cosx + Tanx - Sinx
_______________________________
Sin² x

=>

Sinx × Cosx + Tan x
___________________
Sin ² x

=>

Cos² x + 1
__________
Sinx × Cosx

=>

Cos² x
______
Sinx × Cos x

+ 1/Cosx × Sinx

=>

Cotx + Cosecx × Secx

Hence proved
