Answer 3

oh so like multiplying by one right?

Answer 4

yes

Answer 5

but again I don't really know this stuff so maybe you should wait for more expert advice

Answer 6

okay, thanks :D

Answer 7

you can simplify this
denominator = sin^2 x - 1 = - cos^2 x
numerator = -2

so we get -2 / - cos^2 x = 2 / cos^2 x = 2 sec^2 x

fractions gone!
