how do you find the derivative of this problem and what rule do you use
lim sin(pi+h)-Sin pi
h-> 0 h
lim sin(pi+h)-Sin pi
h-> 0 h
How do you find a dervative of this

… sinπ = 0 …
Hi janemba!
Do you mean [tex]\frac{sin(\pi + h) -sin\pi}{h}[/tex] ?
If so, remember that sinπ = 0, so it's just [tex]\frac{sin(\pi + h)}{h}\,.[/tex]
Which is … ?

It's even simpler than that, take a look at a unit circle and think about what happens with every rotation of pi radians.
