Hello.
I´ve been trying to fix the code, but I couldn’t find what is the problem. As you might see, I want to plot the solution for this PDE, but it’s nowhere to be found. Just the coordinate axes.
I guess the code for the graph is correct, but something is missing. I will grateful if you can help me out. Thanks in advance.
I think you just need a space between the Pi and x terms inside the Sin function.
