Question 1
Which of the following is the correct expression for D'Alembert's solution?
- u(x,t) = f(x + ct) + g(x - ct)
- u(x,t) = f(x - ct) + g(x - ct)
- u(x,t) = f(x + ct) - g(x + ct)
💡 Hint: Remember the forms discussed in the D'Alembert section.
Question 2
The wave equation represents what kind of partial differential equation?
- True
- False
