In 35 and 36 verify that the given function satisfies the wave equation: a2 02 u 0x2 02
Chapter 9, Problem 36(choose chapter or problem)
In Problems 35 and 36 verify that the given function satisfies the wave equation:
\(a^{2} \frac{\partial^{2} u}{\partial x^{2}}=\frac{\partial^{2} u}{\partial t^{2}}\).
\(u=\cos (x+a t)+\sin (x-a t)\)
