1st
bro, this is for 6b, hope you understand my working and where I'm coming from.

I have factorised the answer to its absolute simplest form, which may cause it to differ slightly from your answer key.

ok, this is for 6d.

Same idea as 6b, whereby both qns involve the quotient rule,
but with 6d,
u need to know how to use the trigo formula I have singled out in red at the side of my workings.
