Question

Find the derivative of y= cot x/ (1+cot x)

Answer 1

quotient rule for this one

Answer 2

Ohhh. Right, I forgot about that rule. Its v'*u-v*u'/ v^2 ?

Answer 3

\[\left(\frac{f}{g}\right)'=\frac{gf'-fg'}{g^2}\] with \[f(x)=\cot(x), f'(x)=-\csc^2(x),g(x)=1+\cot(x),g'(x)=-\csc^2(x)\]

Answer 4

thanks!
