Document Summary

Note: information from the pre-requisite, sfwr eng 3dx4 will not be included in this summary (although corrections will be). Soft: performance is degraded but not destroyed. Firm: a few times will simply degrade performance, but after may lead to system failure. Hard: complete and catastrophic system failure: safety critical: may cause injury / death (a type of hard) Backwards difference method: derivatives using x f f x h h f x f x f x h h a a e k.
