sorry, find an expressions for $$d \theta \over d t$$

campbell_st · Answer

$$d \theta/dt = 0.4 \times 600 \cos 600t$$

                       = 240cos 600t

anonymous · Answer

I understand how you got that.

But what about the first one?

campbell_st · Answer

the oscillation is n 600...I think

campbell_st · Answer

oops the oscillation is since the period is 2pi/600

anonymous · Answer

It says 300/pi
