B.5.TU:8 - Common Anti-Patterns and How to Avoid Them

Observed difficulty in the method’s cases	Repair
Reuse a composition while overlooking how many inputs it consumes.	Recover the permitted operations and supply their inputs; in :5.1, copying is the decisive additional operation.
Evaluate a familiar-looking expression before filling its arguments.	Construct the path, derivative and substitution required by the operation, as in :5.2.
Improve a computation whose formulation omits the receiving condition.	Recover that condition and change the model or question; finer calculation of undriven motion leaves departure at rest unresolved.
Discard an infeasible optimizer together with its valid bound.	Interpret each result separately; :5.3 retains the exclusion of value 7.
Require the same depth of study for using and altering a result.	Locate the contribution the work needs, then recover or obtain the reasoning that enables it.
