Hello Mathematicians,
I have a math exercise that has me puzzled.
if H(theta)= (theta)sin(theta), what is H' and H''
I was able to find H', but I have no idea how to address H''. In my class, were were just learning the quotient rule, and we have not went over all of the trig derivatives yet. I have only learned sine, cos, -cos, and -sin. Therefore, any help with the second part would be greatly appreciated.
Here is a copy of my work.

Thank you for your time and knowledge
