Two alternating voltages are given by v1 = 15sinωt volts and v2 = 25 sin (ωt – π/6) volts. Plot both functions on the same axes and hence determine a sinusoidal expression for the resultant vr = v1 + v2.  Check your answer using an analytical method.  Your manager has asked you to analyse the variation in in results between the two methods
