1. State the amplitude (A) the period (T) and the frequency (f) for the periodic function 120sin(100 "pi symbol" t)V
2. Through how many degrees does a wheel rotate in 10ms if its angular velocity is 8 rad/s
3. Sketch one cycle of the given function showing the values of each variable where the curve crosses the axis.
V = 50sin(4.2x10^2t)
I am really sorry for this, but please believe me that I am in desperate trouble if I don't hand these in...
