Play with this applet in order to understand the following: 1. The intial conditions are as stated inside the Applet. Does it make sense to you? That is, given these initial conditions, is the behaviour of this solution conforms with your expectation? 2. If you change n, you can compare the "speed of the wave", that is the frequency. Can you see the relation to the coefficient that multiplies the variable t? You can stop the animation by clicking below on the left.
