Answer:

Step-by-step explanation:

  cos          (1+sin)  

(1+sin)  +     cos

 

=   cos2 + (1+sin)2  

        cos*(1+sin)

 

=   cos2 + 1 + 2sin + sin2  

          cos*(1+sin)

 

we know that cos2 + sin2 = 1

 

=    (1+1+2sin)  

     cos*(1+sin)  

 

=   (2+2sin)

   cos*(1+sin)

 

=      2(1+sin)

     cos*(1+sin)

 

=    2    

   cos  

 

=  2sec
