B.5.MPC.R:4.2 - Recover what each contribution supplies to the next
Start at the mismatch and follow the needed relations in both directions. Ask what the receiving operation takes as input, what the supplied result actually represents and which condition permits that use.
The following questions distinguish common repair locations. Use the ones that can explain the disagreement.
| Connection to inspect | Question that can locate a repair |
|---|---|
| Physical account to mathematical formulation | Which interaction, boundary or operating assumption licenses this equation or constraint? |
| Mathematical formulation to computation | Does the procedure obtain the quantity or property now requested, with the required constraints and approximation? |
| Representation to another representation | Which distinction or operation must survive, and does the correspondence preserve it? |
| Computation to executing arrangement | Can the arrangement prepare the input, perform the operation and finish with the state or result being used? |
| Observation to physical inference | Which physical possibilities can produce this indication under this measurement procedure? |
Explain an unresolved connection in the working notation. Use B.5.RA to recover a needed argument and B.5.RC to recover a construction. C.29.1 compares mathematical transfers; C.29.2 constructs a computation; C.29.3 compares a computation with its realization. Their results answer the corresponding rows, while the physical question determines which row matters.
Keep a common premise visible across different contributions. An analytical calculation and a simulation that both assume no slip leave the same question open when slipping is suspected. A different algorithm is a sufficient alternative only if its premises and output interpretation fit the receiving use.
