Step-by-step explanation:

(secA+tanA)(1-sinA)

(1+sinA/cosA)(1-sinA)

(1+sinA)(1-sinA)/cosA

(1-sin²A)/cosA

cos²A/cosA

cosA

Step-by-step explanation:

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