a voltage is given by v(t)=10sin(1000(pi)(t) + 30 degrees)V
1. use a cosine function to express v(t) in terms of t and the constant pi
2. find the angular frequency
3. find the frequency in hertz to two significant figures and appropriate units
4. find the [hase angle
5. find the period
6.find Vrms
7. find the power that this voltage delivers to a 60(ohm) resistance
8. find the first value after t=0 that v(t) reaches its peak value
