What was d'Alembert's method for obtaining solutions to the wave equation?
d'Alembert's formula
Using polynomial functions
Using the Pythagorean theorem
Integration by parts
Answer
d'Alembert's formula is a solution to the one-dimensional wave equation. It is a combination of two waves, one traveling in the positive direction and one traveling in the negative direction. The formula is: u(x,t) = f(x+t) + g(x-t)
