Answer:
Step-by-step explanation:
That is a true statement.
The first derivative is
[tex]f'(x)=xcos(x)+sin(x)[/tex]
The second derivative is
[tex]f"(x)=-xsin(x)+2cos(x)[/tex]
The third derivative is
[tex]f'''(x)=-xcos(x)-3sin(x)[/tex]
If you don't know how to find a derivative at this point, you'll be in a lot of trouble when it comes to integration. I recommend learning these.
