Answer 1

here is ur answer...first attachment is d answer of ques written by you n second attachment is d answer of ques given in d picture.

Answer 2

Answer:

given that sec a -1/ sec a +1 =1-cos a/ 1+ cos a

to prove LHS=RHS

now, sec a = 1/ cos a

so, (1/cos a-1) / (1/cos a+ 1)

==( 1-cos a/ cos a) / (1+cos a /cos a)  

== 1-cos a / 1+cos a = RHS
