Observation• A Taylor series converges **rapidly near the** point of expansion and slowly (or not at all) at more remote points. 22 23. A truncated quantity is represented by a numeral with a fixed number of allowed digits, with any excess digits "chopped off" (hence the expression "truncated"). https://en.wikipedia.org/wiki/Truncation_error

From examining the symbolic expressions of the truncation error we can add correction terms to the differential equations in order to increase the numerical accuracy. Such cases can be constructed by the method of manufactured solutions, where we choose some exact solution \( \uex = v \) and fit a source term \( f \) in
