Ln(2+sinx) how do u find the derivative

f(x) = cos(x) / (2+sin(x))

Step-by-step explanation:

You gotta use u-substitution. You probably only heard of u-sub from integration, but you can also use it on derivatives as well.

f(x) = ln(2+sin(x))

  I let u=2+sin(x)

So now my new equation is

f(u) = ln(u)

you already know the derivative of ln(u), it's 1/u, but you also gotta multiply it by u' because of the chain rule. So the new equation is

f'(u) = 1/u * u'

substitute your x-values back in to get your answer.

f(x) = cos(x) / (2+sin(x))

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
