Answer 6

it is just fractions work,

you need a common denominator... so multiply the 2 denominators

then cross multiply for the numerators

\[\frac{1}{1+ \sin(x)} + \frac{1}{1 - \sin(x)} = \frac{(1 - \sin(x)) + (1 + \sin(x))}{(1 + \sin(x))(1 - \sin(x))}\]

in the new fraction the denominator is the difference of 2 squares

and just simplify the numerator by collecting like terms.

hope it helps
