  2. Now simplify:


The answer is:

The graph
The first derivative [src]
 5             4       
x *cos(x) + 5*x *sin(x)
$$x^{5} \cos{\left(x \right)} + 5 x^{4} \sin{\left(x \right)}$$
The second derivative [src]
 3 /             2                     \
x *\20*sin(x) - x *sin(x) + 10*x*cos(x)/
$$x^{3} \left(- x^{2} \sin{\left(x \right)} + 10 x \cos{\left(x \right)} + 20 \sin{\left(x \right)}\right)$$
The third derivative [src]
 2 /             3              2                     \
x *\60*sin(x) - x *cos(x) - 15*x *sin(x) + 60*x*cos(x)/
$$x^{2} \left(- x^{3} \cos{\left(x \right)} - 15 x^{2} \sin{\left(x \right)} + 60 x \cos{\left(x \right)} + 60 \sin{\left(x \right)}\right)$$
