Electromotive Force In an electric circuit, suppose that the electromotive force in volts at \( t \) seconds can be modeled by \(V = \cos 2 \pi t\)Find the least value of \( t \) where \( 0 \leq t \leq \frac { 1 } { 2 } \) for each value of \( V \) . (a) \( V = 1 \) (b) \( V = 0.87 \) (c) \( V = 0.31\) 

Answer

a) t = 0 , b) t= 0.082 , c) t = 0.2
