Issue with Conservation Laws and Heat Flow Lab Volume 4
Page number and/or relevant section in lab: Page 89, second equation after Implicit Methods title
Description of issue: The error in the second term should be O(delta t^2) (instead of O(delta x^2)) as we are using the midpoint method in the time coordinate.
Additional Thoughts: It wouldn't even make sense for the error to be in terms of delta_x has the equation involves no differences in the x-coordinate. The O(delta x^2) error doesn't appear until we make a finite difference approximation of the second spatial derivative of u.
