risen.) in a certain kind of electrical circuit, the current {{t) measured in amperes at time t seconds is given by JG) = m cosuzu rrt + g). [a] Change the form of the function Ht} to the sine iunction form given in: t) = A sin(mt + 4i}. {bi Give the period of the sine function in part [a] and the phase shift. Use the sine function to sketch two cycles of the graph I (t)
