could you please answer q3 with detailed steps, thanks!
He linear advection equation tr the following scheme , where a is a positive constant is solved u...
6. Consider the Cauchy problem for the advection equation, u +cu0, where c>0 a) Expand u(z,t + k) in a Taylor series up to O(k3) terms. Then use the advection equation to obtain c2k2 uzz(x, t) + O(k"). u(z, t + k) u(x, t) _ cku(x, t) +- b) Replace u and ur by centered difference approximations to obtain the explicit scheme This is the Lax-Wendroff method. It is von Neumann stable for 0 < 8 < 1 and it...
