Two sound waves, producing the pressures P1 = 6 sin(4007tt) and P2 = 8 cos(4007t), combine on a person's ear drum to produce the pressure P = P1 + P2. Graph P in [-0.01, 0.01, 0.001] by [-20, 20, 2] and use the graph to estimate values for a and k so that P = a sin(400 Ttt + k). Round k to the nearest ten-thousandth, if necessary. %3D
