How do you differentiate y=(2+sinx)/(x+cosx)?
I'm assuming I use f(x)/g(x)=((f'(x)g(x)-(f(x)g(x)))/[g(x)]^2), but I can't seem to get it to work for me. How exactly would I do something like this?

dy/dx =
Explanation:
Use the quotient rule to derive the following:
y' =
y' =
multiplying the numerator out gets you this:
y' =
then the only simplification you can use is the trig identity
to get:
y' =
y' =
