The function is f(x) = sin(2x). Find f'(x) and then f''(x). What is the largest possible value of f''(x)?

so because sin 2x cannot be more than 1 between the pi/2 and 0??

Error Estimating
sin(x) oscillates between 1 and 1. Check on the TI.
Also, sin(nx) , such as sin(3x) , just increases the frequency I think. You can graph that too. It just squooshed the oscillations closer to the yaxis. So they are still in between 1 and 1.
