Calc1231W1T5 - The Wave Equation Current Grade: 13.3 / 20.0 Remaining Time: 91:45:06 Question 4 The function u(x, t) = er(a+ct) is another solution to the wave equation 4 points azu _202 ul = 0 at2 How Did I Do? Let's investiage the case when c = 2 + 52 . Then . The real part of u is . The imaginary part of u is So the function oscillates in the complex plane, but these oscillations are dampened by the exponential term. As time goes on lim u(x, t) = 0 Submit Assignment Quit & Save Back Question Menu N
