we \: have \: an \: identity \\  \\  \\  \\  {sec}^{2}   \theta \:  -  {tan}^{2}  \theta \:  = 1 \\  \\  \\ and \\  \\  {x}^{2}  -   {y}^{2}  = (x - y)(x + y) \\  \\  \\ now \\  \\  \\  \sqrt{(sec \theta - 1)(sec \theta + 1)}  \\  \\  =  \sqrt{ {sec}^{2}  \theta - 1}  \\  \\  =  \sqrt{ { \tan}^{2} \theta }  \\  \\  = tan \theta

hope it helps
