Question 1
What is the general form of 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,t) + g(x,t)
💡 Hint: Think of the waves moving in opposite directions.
Question 2
True or False: The wave equation is a first-order differential equation.
- True
- False
💡 Hint: Consider the orders of derivatives in the equation.
