The first derivative [src]
          4       
     5*log (x + 9)
-5 + -------------
         x + 9    
$$-5 + \frac{5 \log{\left(x + 9 \right)}^{4}}{x + 9}$$
The second derivative [src]
     3                        
5*log (9 + x)*(4 - log(9 + x))
------------------------------
                  2           
           (9 + x)            
$$\frac{5 \left(4 - \log{\left(x + 9 \right)}\right) \log{\left(x + 9 \right)}^{3}}{\left(x + 9\right)^{2}}$$
The third derivative [src]
      2        /       2                      \
10*log (9 + x)*\6 + log (9 + x) - 6*log(9 + x)/

                           3                   
                    (9 + x)                    
$$\frac{10 \left(\log{\left(x + 9 \right)}^{2} - 6 \log{\left(x + 9 \right)} + 6\right) \log{\left(x + 9 \right)}^{2}}{\left(x + 9\right)^{3}}$$
