 \frac{1 + sec \theta - tan \theta}{1 + sec \theta + tan \theta}  \\  \\  =  \frac{( {sec}^{2}  \theta -  {tan}^{2}  \theta)  + (sec \theta - tan \theta)}{1 + sec \theta + tan \theta}  \\  \\  =  \frac{(sec \theta - tan \theta)(sec \theta + tan \theta + 1)}{1 + sec \theta + tan \theta}  \\  \\   = sec \theta - tan \theta \\  \\  =  \frac{1 - sin \theta}{cos \theta}
