can someone please show all the steps to this question. thanks !!

4. The voltage signal from a standard European wall socket can be described by the equation V(t) = 130 sin[(1 + C)nt], where t is time, in seconds, and V is the voltage at time t. Find the maximum and minimum voltage levels and the times at which they occur. Make sure you clearly indicate the max/min values with their corresponding times. C - 8
