(1) The voltage of the electricity supply in North America can be modelled using a sine function. The maximum value of the voltage is about 120 V, and the minimum value of the voltage is about (-120) V. The frequency is 50 Hz. (Hz = Cycles/seconds) (a) What is the amplitude of the model? (b) What is the period of the model? (e) Determine the equation of the model in the form ya sinks. JAIS]
